2. Safety and Precautions- Use Contrac power electronics EAS 822, EBS 852, and EBS 862 for driving the

Contrac control actuators specified on the electronics ID label, only.- Prior to maintenance or repair works always disconnect the electronics from mains

and secure the respective control actuator against reactive process forces.- All installation and maintenance works must only be performed by qualified special-

ists who have been trained for these tasks.- Observe the locally valid accident prevention regulations and the regulations con-

cerning works on electrical equipment.

3. Transport and StorageContrac electronics may be stored under moist and aggressive condition for a shorttime. The equipment is protected against external corrosive influences. However, directexposure to rain, snow, etc. must be avoided.Interior areas of the actuator with risk of condensation are protected by desiccant.

Desiccant in electronics: . . . . . . . . . . terminal boxTransport temperature: . . . . . . . . . . . .-30° C … + 80° CStorage temperature: . . . . . . . . . . . . .preferably 0° C … + 40° C

The desiccant guarantees sufficient protection for approximately 150 days. It can beregenerated at a temperature of 90° C within 4 h.The desiccant must be removed prior to commissioning the actuator or the electronics.The mounting rack must only be transported empty and by no means with installedelectronic units.

4. Features- Continuous positioning of Contrac control actuators- Processor-controlled power electronics using the frequency converter principle- Installation in mounting rack in electronics rooms- Protection class IP 20- Power supply 230 V AC or 115 V AC; single-phase- Conventional signal interface (0/4 … 20 mA and binary 24 V)- Digital communication via RS 232 and FSK / HART- Easy installation and commissioning- Simple configuration and parametrization using a configuration program- Adjustable motor torque and speed- Additional functions, e. g. process controller, maintenance manager, programmable

characteristic curve / split range

5. GeneralElectronics of three different sizes are available for the Contrac actuator series. Theelectronics can be adapted to the respective actuator type using special parameters.They are the interfaces between process control systems and actuators/ valves. The actuators / valves are continuously positioned, independent of the input signal type(analog or digital). During positioning the motor torque is continuously changed without steps, until theforces between control actuator and valve are balanced.High positioning accuracy combined with excellent control performance and long life-time are achieved even for changing load situations and short actuation times.

5.1 MountingThe electronics unit is designed for rail-mounting in a special rack providing fourmounting levels. Either four units (EAS 822 and / or EBS 852) or one unit (EBS 862) canbe accommodated on each level. It is also possible to mix the units, as seen in figure 1on page 5. Do not transport the rack with the units installed; the total weight is too high.Mains supply and accommodation of fuse units and junction boxes are as shown in fig-ure 13 on page 17. From there the cable connections are routed to the electronics units.

5.2 Design

5.2.1 ElectronicsThe aluminum cases of the electronics are mounted to four stay bolts on the mountingrails. The units are installed, electrically connected and operated from the front.

4

5.2.2 Mounting RackThe rack is an open steel profile rack. Regarding construction and dimensions it is sim-ilar to commercially available electronics cabinets (e. g. Contronic cabinet).

5.3 LabelingThe mounting racks can be labeled in a headline with approximately 20 characters. Vertically the four levels are designated with letters A, B, C, and D, resulting in a matrixof max. 4 x 4 mounting locations.

9. SetupThe basic settings (definition of end positions) can be made via the Local Control Panel(LCP). It is used for adapting the actuator to the operating range and the effective di-rection without a PC. The actuator can be set up and configured completely using theappropriate configuration program.The commissioning and service field is located on the electronics!

9.1 Setup via LCP

9.1.1 Operating elements1. Write-protect switch (Default setting: OFF)2. LED for 100% position Indication if adjustment procedure, saved position, or

fault by different flash frequencies.3. Drive buttons Press to cause drive motion4. Reset button Press to restart processor and clear any 0% and 100%

values.5. Power LED Indicates available mains supply6. RS 232 socket Connection socket to PC7. Potential toggle switch Connection of reference potential to the system or pro-

tective earth (by default set to system)8. LED for 0% position Indication if adjustment procedure, saved position, or

fault by different flash frequencies..9. Accept button (0%) Press to define current position as 0%; simultaneously

press push button 11 to complete the adjustment proce-dure.

10. Accept button (100%) Press to define current position as 100%; simultaneouslypress push button 10 to complete the adjustment proce-dure

Figure 15: Local Control Panel (LCP)

The actuator range is not preset in factory!

9.1.2 Initial situation- Electronics connected to power supply and actuator- Write-protect switch (1) set to “OFF” position- Electronics in operating mode “MAN” (no signal on DI 1)- No fault (if a fault occurs, both LEDs flash alternately at 4 Hz)

9.1.3 Setup procedure- Undo the screws of the LCP cover- Swing the cover to the side

9.1.3.1 “Setting” mode- Set electronics to “setting” mode by pressing both push buttons (3) simultaneously

for approx. 5 seconds, until both LEDs (2 + 8) are flashing synchronously at approx.4Hz.

9.1.3.2 Defining first position (0% or 100%) (Higher precision in 2ndposition)

- Move to desired position by pressing one push button (3).- To accept the position, press push button (10) or (9); the associated LED flashes at

approx. 1Hz when value is correctly accepted, the other continues to flash atapprox. 4Hz

9.1.3.3 Defining second position (0% or 100%)- Move to second position by pressing one push button (3).- To accept the position, press push button (10) or (9); both LEDs (2) and (8) are flash-

ing at approx. 1Hz when value is accepted correctly.

9.1.3.4 Saving the settings- The settings are accepted by simultaneously pressing the push buttons (10 + 9); the

LEDs (2 + 8) extinguish after a short time, and the adjustment procedure is complet-ed.

- If the selected range is too small for the actuator, both LEDs will flash again at 4Hz.Repeat the adjustment procedure a larger value (min. positioning travel).(See positioning travel specification on actuator ID label)

9.1.3.5 Correction after setup- If the setting is to be corrected after accepting the first value, first press the Reset

button (4) and then repeat the setting.- If the correction is to be done after saving the settings, the entire adjustment proce-

dure must be repeated.

9.2 Adjustment using the configuration programContext-sensitive help information is available in the configuration program at all times.For basic handling and installation instructions refer to the associated manual, number41/68-001.A conductive ground connection is established between the PC and the CONTRACelectronics with the RS 232 communication cable. If the PC is grounded, this may causea ground loop in the installation.

9.3 Indication at LCPFunction Indication

AdjustmentChange-over to adjustment mode:Press and hold both drive switches for approx. 5 seconds

Both LEDs flash synchronously at approx 4Hz after time has expired.

Moving to an end positionUse respective drive button on CSF

Both LEDs continue to flash at 4Hz while driving.

Saving the first end positionPress button 0% or 100%

The associated LED flashes at approx. 1Hz, the other continues at 4Hz.

Saving the second end positionPress button 0% or 100%

The associated LED flashes at approx. 1Hz synchronously to the first one.

Terminate adjustmentPress 0% and 100% buttons simulta-neously

Both LEDs are briefly lit together and then extinguish.

OperationNormal operation: MAN / AUT LED offDriving with button on CSFPriority over control system

LED off

Fault (both LEDs flash alternately at 4Hz)Reset:Resets fault indications

If no other fault conditions exist, both LEDs extinguish.

Reset if operating range is exceeded;press and hold both drive button for 5 sec-onds, then press Reset button

After approx. 5 seconds the flash rhythm is briefly interrupted. After “Reset” the electronics switch to adjustment mode.
