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:
- Set Stand by with function: E Rra or
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
Control alternating mode (the switching state contact "open" or "closed" allot to two different
-
setpoint temperatures): E r1B or
- 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
