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 carrier liquid:
E E0K
or
Refill
.
