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)
MAINS 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 MAINS
(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 a trained operator using the appropriate
password.
NOTE !
The programmable signals on
X1
will be disabled with
Q1
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)
