3. Adjustments and CalibrationAfter installation has been completed, all chapters relevant for your monitor must be read and understood to ensure correct functionality of the RCM. When adjustments has been completed, set the monitors in a safe parked position to ensure that activation does not factor a risk.

3.1 Monitor TypeThe RCM is made for both SAFE area and with ATEX equipment and comes in several different combinations. For the ATEX monitors the operation and maintenance are the same with the exception of the nozzle (EON) where the settings differ (see “3.5.2 ATEX Nozzle Settings” on page 8). The type of monitor can be identified by the combination of letters that follows the size designation. The following combinations can be read from the full model number:

Example: RCM-150 EL DIN EX POS EON-140

1. RCM-xxx EL- Size of monitor2. DIN/ANSI - Type of connection 3. EX - Only present if monitor has ATEX equipment4. POS - If monitor has positioning system - Check “3.3 POS - Positioning System” on page 64. LS - If monitor has limit switching - Check “3.4 LS - Limit Switching” on page 75. EON-xxx - Size of nozzle - Check “3.5 Nozzle Settings” on page 8

3.2 Mechanical Movement LimitationThe RCM is delivered without any mechanical stops to allow for maximum movement and ease of installation. If however a mechanical stop of rotation is needed, one of the connecting bolts can be flipped as shown below.

3.3 POS - Positioning SystemThe RCM EL with POS uses pulse counting as a method for giving precise angular measurement of rotation and elevation of the moni-tor. The RCM POS is used where exact positions are needed such as in automated systems.

The POS version of the RCM is installed according to installation in-struction with document number: II-0005-RCM-POS-EN

3.3.1 Electrical InstallationBefore switching on power, make sure that each monitor has been connected in accordance with the orders associated External Wiring Diagram and that the PLC has the correct program installed to be able to read the position given by the monitor. This should be carried out by authorized staff only.

3.3.2 Positioning SettingsZero position as well as maximum positions are set via software in the PLC panel provided by Incendium. The program uses a reset position as origin of movement and it is crucial that this origin is set correctly. Depending on the situation in which the RCM POS is used, the monitor should point toward the centre of the protected area in regards to rotation and at 0° elevation/horizontal as shown to the right.

Depending on the size of the monitor, the pulses given for movement differs in terms of degrees moved. Using a system from Incendium, zero position is always 1000 pulses elevation and 1000 pulses rotation.

Use the table below when setting position limits. For degree specific setting, divide wanted angle position with [°/pulse] value for the given monitor and round down. Example: RCM-80 elevation up +50°: 50°/ 0,74°= 67 pulses

POSITION LIMITING PULSES/DEGREES

Model Rotation[°/pulse]

Max rotation right +180°[pulses / PLC setting]

Max rotation left -180°[pulses / PLC setting]

Elevation[°/pulse]

Max. elevation up +70°[pulses / PLC setting]

Max. elevation down -90°[pulses / PLC setting]

RCM-80 0,98° 184 / 1184 184 / 816 0,74° 94 / 1094 94 / 906

RCM-100 0,76° 236 / 1236 236 / 764 0,62° 113 / 1113 113 / 887

RCM-150 0,52° 344 / 1344 344 / 656 0,45° 155 / 1155 155 / 845

Take note that manually overriding rotation or elevation also bypasses the positioning system. This means that a reset on zero position must be made after overriding.

Revision: 18E23


3.4 LS - Limit SwitchingThe RCM EL with LS uses limit switches to set maximum elevation and rotation positions. The RCM LS is used mainly in manual systems where only outer limits are needed to protect surrounding structure or to limit the allowed extinguishing area of the monitor.

The LS version of RCM is installed according to installation instruction with document number: II-0004-RCM-LS-EN

3.4.1 Electrical InstallationBefore switching on power, make sure that each monitor has been connected in accordance with the orders associated External Wiring Diagram. This should be carried out by authorized staff only. If installed incorrectly, the monitor or surrounding structure could take damage.

3.4.2 Setting Limits RotationIf installed correctly according to installation instructions, the RCM LS monitor should point toward the centre of the protected area in regards to rotation. Limiting rotation is done by moving two hexagon domed nuts to the relative position where right and left motion is desired to be stopped. As shown to the right, rotation left is stopped by the closest nut (2) to the right of the dual limit switches(1). This is because the switches are the ones that are moving and not the stops themselves. To limit the rotation, move the two hexagon domed nuts to the desired posi-tions. The manual override handle can be used to aid in this proce-dure (replace after use according to 2.1).

In addition to moving the domed nuts, the entire stop plate can be rotated by slightly loosening the screw (3) and nut (4) fixation around the monitor base. Re-tighten, being careful not to bend plate, after adjusting.

3.4.3 Setting Limits ElevationThe RCM LS is normally delivered with elevation limiting nuts (5,6) set to absolute maximum (+70°, -90°). If further limiting is desired, these nuts can be loosened and tightened in the desired position. In the example below, the nut for limiting up-wards motion is stopped at +50°. The upper nut (5) is loosened slightly and moved down to the dual limit switches (7) until it audibly clicks. The nut can now be tightened resulting in a maximum upward elevation of 50°.

3.5 Nozzle SettingsThe RCM consists of the monitor base (RCM) and the nozzle (EON). Each size of RCM has two possible nozzles that can be used depending on the pressure and flow required.

3.5.1 Standard NozzleAs standard the nozzle comes with a linear actuator 24VDC which is used for maneuvering between fog (wide water spray) and jet (directed water jet). The linear actuator is equipped with a potentiometer which allows for precise setting of the water stream. It is also equipped with internal switches that provides automatic stopping function at maximum fog and maximum jet.

3.5.2 ATEX Nozzle Settings The ATEX nozzle (EON) consists of the standard type nozzle and a mechanical linear actuator (1) in combination with a three-phase motor (2) and limit switching (3) for fog-/jet operation (instead of a 24VDC linear actuator). The flow/pressure setting is however the same as for the standard nozzles.

Calibration of fog-/jet setting is done at factory but if changes needs to be made the following settings can be made. Adjust-ing the hexagon domed nut (4) up and down changes the trigger depth of both limit switches (3). Upwards adjusted domed nut (4) equals earlier triggering which means that stop for fog happens earlier (movement of outer pipe backward is stopped earlier) as well as for jet (movement of outer pipe forward is stopped earlier). Opposite movement of domed cap achieves the a later triggering by the same principle. The switches (3) can also be adjusted independently by loosening the bolt connection (5) holding each switch in place. The trigger depth can then be adjusted by moving the limit switch (3) down for earlier triggering and up for later triggering. The bolt connection (5) is then tightened carefully at desired position.

3.5.3 Flow SettingNormally, the EON is calibrated in factory according to the pressure and flow specified at the time of purchase. Changing this calibration can however be required on site when the pressure or flow differs from what has previously been stated. The capacity of the nozzle is adjusted by turning the nozzle disc, increasing or decreasing the opening. For specific pressure and flow per turns of disc information, see the specific size of nozzle section.To adjust the nozzle opening, unscrew the counter-locking nut (2) holding the disc (1) in place. Turn disc clockwise until contact with nozzle outlet and make a mark (3) to be able to easily count rotations. Turn disc (1) counter-clockwise until, as specified for the nozzle in question, enough rotations has been achieved. Tighten counter-locking nut (2) while holding the disc (1).

If the flow is adequate, but the throw length is lacking, the pressure needs to be increased. This can be done by turning the disc inwards and testing intermittently until good result has been achieved.If the throw length is good, but the flow is lacking, the flow needs to be increased. This can be done by turning the disc out-wards and testing intermittently until good result has been achieved. If any problems still persists, contact Incendium for assistance.

3.7 Functional TestPay attention to potential hazards according to “2. Hazard warning” on page 4 before proceeding.All monitors should be tested for correct functionality via the control panel and the hand-held radio control (if supplied). When performing these tests, make sure that the water connection is closed and that personnel are aware of the tests taking place. When oper-ating from the control panel, at least one person should survey that the monitor moves in accordance to signals sent.

As with all three-phase motors, phase sequence can differ from site to site. All monitors should be checked for movement in the desired direction. If the monitor behaves differ-ently than expected, flip the sequence in the connection box until desired result has been achieved.

3.7.1 Test for RCM LS and EXWhen a monitor has any fixed limits, such as with RCM LS or when monitor has an ATEX Nozzle with stops for jet and fog, functionality can be tested easily. After the monitor has been connected according to the external wiring diagram, the moni-tors need to be tested for correct function. Correct rotation and elevation stopping of the monitor with LS can be tested by triggering the switch in question for each movement. Use a screwdriver or similar tool when triggering the switches to avoid pinching hazard. If movement does not stop when the correct trigger is pushed the connection is for some reason faulty and must be checked according to the external wiring diagram.

Rotation LS: When moving the monitor to the left, trigger the right switch (seen from behind the monitor) by pressing the wheel arm until it audibly clicks. Test the reverse situation as well.

Elevation LS:When moving the monitor up, trigger the upper limit switch by pressing the wheel arm until it audibly clicks. Test the reverse situation as well.

Nozzle EX:When moving the nozzle from fog to jet position, press the foremost switch until it audibly clicks. Test the reverse situation as well.

3.7.2 Test for RCM POSIf the RCM in question has POS, it also comes with a PLC panel to which there are separate instructions that must be read. The POS function is not direction sensitive and must therefore be checked for correct movement after installation. If the monitor does not move according to input, the connection is for some reason faulty and must be checked according to the external wiring diagram.

Check that the zero position is horizontal for elevation and that the monitor is pointing towards the center of protected area (zero position 1000:1000). Before testing maximum limits, first check that the pulse settings in the control panel corresponds with the table in chapter “3.3.2 Positioning Settings” on page 6. Make sure that max limits for elevation does not exceed the values given in this table. Rotation values can be set above the maximum limits of the table but only with supervision of the monitors movements (first time setting) to make sure that cable hose or other equipment is not damaged.

Take note that manually overriding rotation or elevation does also bypasses the positioning system. This means that a reset on zero position must be made after overriding.

In some cases the RCM POS also has EX functionality. If so, check the previous chapter for setting the EX nozzle.

For all other questions, please contact Incendium.

Make sure that the cable on the back of the monitor is in the shown position to ensure no harm will come to it during operation.

6. General Troubleshooting• Monitor does not move properly when given signals: o Check to see if monitor is in the expected starting position. o Check trigger and limit switches for damage. o Check for debris in gear and remove if present. Power must be disconnected during this operation. o Check if gears for rotation or elevation contain enough grease. o Check if monitor, motors or gears has damage. o Check emergency motor break switches and reset if triggered.• The monitor is leaking: o If leakage is coming from the flange of the monitor, check if all bolts have been properly tightened. o If leakage occurs from joints in the monitor the o-rings might need to be switched out. Contact Incendium. o If leakage occurs from joints between monitor and nozzle the two nuts on the groove coupling can be tightened.• The monitor produces an uneven jet or fog: o Check for debris inside nozzle. If debris is present, unscrew the nozzle disc and flush the monitor according to chapter 4.2. Then put back the nozzle disc at the same amount of turns as before. • The jet from the monitor is shorter than expected or weak: o Check that the pressure provided to the monitor is correct. o Adjust the nozzle disc according to chapter “3.5 Nozzle Settings” on page 8.• The nozzle does not maneuver as expected:

o Maneuver the nozzle from fog to jet several times. o Check for debris inside nozzle. If debris is present, unscrew the nozzle disc and flush the monitor according to chapter 4.2. Then put back the nozzle disc at the same amount of turns as before. o If the nozzle is of ATEX type, check for any problems with the mechanical actuator. If it has locked up and the plastic plug on the bottom has dropped out, the connection of motors or limit switches might be faulty and must be inspected. The actuator can unlocked by unscrewing the front screw and rotating the push piston counter-clock wise. The plastic plug on the bottom of the actuator can then be pushed back again and the screw fixing the push piston can be reinserted.

Contact Incendium if any problems persist.
