Installation and Operations Guide
Connections and Configuration
WESTERM For connections to the WESTERM D20C for status input wetting, use TB1-1 and
D20C: External TB1-51. TB1-2 is for either a connection accepting an external positive supply for
DC & Control control outputs or as an output connection for sourcing the internal control output
Output Supply common:
Jumpers Z2 and Z3 must be set for external supply source. Jumpers Z4 and Z17 must
be set for TB-2: for either and external (+) polarity supply for control outputs to
interposing relays or for outputting the internal supply common (-).
Since bipolar status inputs are allowed, the polarity of the external supply is
irrelevant. Fuses F2 and F3 provide fusing on each leg of the supply.
