5.7 Dry Contacts
On the uppermost green plug of the Controller module, on the right side of the plug, there are four
alarm contacts. We describe them here, in right-to-left order.
Figure 33: Dry contacts on rear of controller
1. The first contact on the right is COM. It is used with several of the other contacts.
2. The second contact from the right informs on the status of the BATTERY circuit breaker.
This contact is used together with the first COM contact. This contact is normally closed.
When the BATTERY circuit breaker is turned off (opened), the contact opens, and an alarm
is generated.
The alarm is shown in the log display as “BATT CB”, and is number 25 in the Power+’s list
of alarms.
If this optional feature has been ordered, then in the factory, two BATT CB dry contacts are
connected to the two special-purpose terminals labeled "Bat. CB".
To make use of this BATT CB alarm, the customer must connects the two special purpose
terminals labeled "Bat. CB" to the auxiliary contacts of the circuit breaker or switch of his
battery cabinet. The auxiliary contacts on his battery cabinet switch must be Normally
Closed.
3. Contact “NC1”, normally closed, is the third contact from the right on the green plug. This
contact is used together with the first contact, COM, and reports the status of the lightning
protection. When NC1 is closed, this means that the lightning protection is OK; when NC is
open, the lightning protection is NOT OK.
When this contact opens, the event is listed in the alarm display as USER-1. This is alarm
number 17 in Power+’s internal list of alarms.
4. The fourth contact from the right is NC2. NC2 is used with the first COM contact to report
the status of the OUTPUT circuit breaker. When the OUTPUT circuit breaker is turned off
(opened), the NC2 contact opens and an alarm is produced. The alarm appears in the
system alarm display as USER-2.
