9.1.3 Output signals on voltage-free contacts
The interface board provides 6 voltage free relay contacts giving some UPS critical alarms and
operation mode.
These signals are available either on connector J2- (sub D, female 25 pin) or terminal blocks X1.
The meaning of the alarms on the free contacts in standard configuration (default) is the following:
X1 / 1, 2, 3
or
J2 / 1, 2, 3 (NO, C, NC) Mains Failure
(def. Parameter RL=1)
X1 / 4, 5, 6
or
J2 / 4, 5, 6 (NO, C, NC) Load on Inverter
(def. Parameter RL=3)
X1 / 7, 8, 9
or
J2 / 7, 8, 9 (NO, C, NC) Stop Operations
(def. Parameter RL=5)
X1 / 12, 13, 14
or
J2 / 14, 15, 16 (NO, C, NC) Load on Mains
(def. Parameter RL=2)
X1 / 15, 16, 17
or
J2 / 17, 18, 19 (NO, C, NC) General Alarm
(def. Parameter RL=4)
X1 / 18, 19, 20
or
J2 / 20, 21, 22 (NO, C, NC) 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 and J2 will be disabled with Q1 open, with the
exception of the signals for “16 - Manual Bypass Q2 ON” and “26 - EPO”.
9.1.4 Programmable input free contacts
Some programmable UPS functions (indicated in Section 9.1), can be activated by closing an external
contact, if connected, on:
X1 / 10, 21 or J2 / 10, 23 User Input 1 (default = Not used)
X1 / 11, 22 or J2 / 11, 24 User Input 2 (default = Emergency GEN ON)
