4 Installation guide4.1 Electrical connection

Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-fied personnel in compliance with the applicable national and international standard EN 60204-1and any other EU standards that are applicable in Europe.

The installation of a power supply isolator is required for each motor and power supply to facilitatevoltage-free work on the electrical equipment. The power supply isolator is not included.

Item Function Description(A) CAN EXT-

TERMOFF/ON

CAN bus termination. If the CAN bus module is the last node on the CAN bus, the

jumper must be set to (ON) .(B) OFF/ON

EMERGENCYOPENING

Jumper is set to (OFF).

Jumper is set to (ON), if supply from emergency opening is mounted on L6 RS.(C) CAN INT-

TERMOFF/ON

Internal CAN bus termination must always be set to (ON) when the CAN busmodule is mounted in DOL 100.

When the CAN bus module is mounted in a house controller, see the section SettingCAN termination jumpers [} 11].

(D) RXD LED shines (green) when data is received on connection terminals L7 to L12.(E) TXD LED shines (red) when data is sent from connection terminals L7 to L12.

4.1.4 Setting CAN termination jumpersThe modules are controlled via CAN bus communication. It is important that the CAN termination jumpers areset correctly in order to achieve secure communication between the modules. The jumper must be ON on themodule where communication ends.

4.1.4.1 House controller without I/O modules1. Set the jumper ”ON/OFF CAN TERM” to OFF (main module).2. Set the jumper ”ON/OFF TERM” to ON (external box).3. Set the jumper ”ON/OFF INT-TERM CAN” to ON (CAN bus module).4. Set the jumper ”ON/OFF EXT-TERM CAN” to ON (CAN bus module).

5 Troubleshooting guideErrorNo light in RXD (green) and TXD(red) LED on CAN bus module.

Check for 24 V DC socket J40 or J41 on the CAN bus module, see thesection Connections on CAN bus module [} 9].

TXD (red) LED shines. No light inRXD (green) and on CAN bus mod-ule.

No data is received from the CAN bus.

Check that the CAN bus cable is connected correctly and that power isbeing supplied to the production controller.

External box does not appear asconnected in the climate/productioncontroller.

Check that the correct addresses are selected on the I/O modules.Check resistance between CAN-Hi and CAN-Lo, the resistance must beapproximately 60 ohms.

If the resistance is > 100 ohms, a termination is missing.

If the resistance is < 45 ohms, there are too many terminations.

All units connected to the CAN bus must be measured without powersupply.

Check the jumper settings, see the section Setting CAN terminationjumpers [} 11].
