* Operating mode is selected by jumper DI1/DI2 - closed for “dry contact” and open for “logic
level”. By default, jumpers are closed.
5. LED indicators
The following indicators show the status of the controller:
• Relay1/Relay2 (green) – these LEDs are illuminated whenever the corresponding relay
is activated (the NO contact is closed and the NC contact is open);
• Sts (red) – flashes when the main program of the controller is executed;
•
Log (yellow) – ON when somebody is logged via the WEB interface, flashes on 2
seconds when the client and server are connected;
• Net (green/red) – red when the device is linked, yellow when there is an activity.
6. Powering
TCW122B-RR is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for use
in the conditions of overvoltage category II, and priorly assessed for compliance with safety
requirements. The power supply equipment shall be resistant to short circuit and overload in the
secondary circuit.
