8.5 Contact module
8.5.1 Contact module LRZ 915 with three inputs and three outputs
Contact module Cat. no. LRZ 915) on 15 pole SUB-D socket. With three relay contact outputs
(changeover, max. 30V/ 0.2A) and three binary inputs for control via external voltage-free contacts.
The following functions are made available by the inputs:
- Set fault with function: Master: E @K@ or Command: Fault .
- Set Stand by with function: E Rra or Stand by .
- Control programmer (Input 1 activates programmer 1, input 2 activates programmer 2 etc. At the
first “close” the programmer gets starting, “open” removes it in “pause”. The next “close” initiate
“continue”) with function: E Op5 or Programmer .
- Control alternating mode (the switching state contact “open“ or “closed” allot to two different
setpoint temperatures): E r1B or alternating mode .
- Controller mode (the switching state input “open” or “closed” can allotted to two different control
temperature sources. E. g. internal ↔ external control): E Bml or type of control .
The following functions are made available by the outputs:
- Signal various fault states: E ch@ or fault diagnosis .
- Signaling standby: E Rra or Standby .
- Providing status of the window discriminators (inside ↔ outside): E VWh or temperature
range .
- Providing the programmer status: E Op5 or Programmer .
- Signaling refill of heat transfer liquid: E E0K or Refill .
