X1 terminal block - Output signals on voltage-free contacts
The Customer Interface board provides
6 voltage free relay contacts
giving some UPS critical alarms and
operation mode.
These signals are available on terminal blocks
X1
. Max. rating terminals:
AWG 17 /
1mm
2
.
The meaning of the alarms on the free contacts in standard configuration (default) is the following:
X1 / 1, 2, 3
(NO, C, NC)
UTILITY FAILURE
(def. Parameter RL=1)
X1 / 4, 5, 6
(NO, C, NC)
LOAD ON INVERTER
(def. Parameter RL=3)
X1 / 7, 8, 9
(NO, C, NC)
STOP OPERATION
(def. Parameter RL=5)
X1 / 12, 13, 14
(NO, C, NC)
LOAD ON UTILITY
(def. Parameter RL=2)
X1 / 15, 16, 17
(NO, C, NC)
GENERAL ALARM
(def. Parameter RL=4)
X1 / 18, 19, 20
(NO, C, NC)
BUZZER (ACOUSTIC ALARM)
(def. Parameter RL=6)
In case different alarms or operating status are required, they can be configured on the same terminals via
software from the Control Panel.
The configuration can be changed in parameters mode by an ABB Service Technician using the appropriate
“Service Code”.
Note!
The programmable signals on X1 will be disabled with “Q1 – UPS output switch” open, with the
exception of the signals for “16 - MANUAL BYPASS ON” and “26 – EMERGENCY ON (EPO)”!
5.2.2
X1 terminal block - Programmable input free contacts
Some programmable UPS functions (indicated in Section 9.2), can be activated by closing an external contact, if
connected, on:
X1 / 10, 21
User Input 1 (default = Not used)
X1 / 11, 22
User Input 2 (default = GENERATOR ON)
