4.1.1Serial Port J3

Serial port J3 - RS-232(sub D, female 9 pin) that allows:

•Total remote management of the system using new generation software JUMP (Java Universal Management Platform) for system protection and management of systems using GE Industrial Systems UPS’s.

JUMP system is written in JAVA and supports virtually all platforms having JAVA runtime environment version 1.1 or higher.

The serial port J3 - RS-232is enabled on all the units of the parallel system.

4.1.2Output potential free contacts

The interface board provide 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)

Utility Failure

(def. Par. RL=1)

X1

/ 4, 5, 6

or J2 / 4, 5, 6

(NO, C, NC)

Load on Inverter

(def. Par. RL=3)

X1

/ 7, 8, 9

or J2

/ 7, 8, 9

(NO, C, NC)

Stop Operations

(def. Par. RL=5)

X1

/ 12, 13, 14

or J2

/ 14, 15, 16

(NO, C, NC)

Load on Utility

(def. Par. RL=2)

X1

/ 15, 16, 17

or J2

/ 17, 18, 19

(NO, C, NC)

General Alarm

(def. Par. RL=4)

X1

/ 18, 19, 20

or J2

/ 20, 21, 22

(NO, C, NC)

Acoustic Alarm

(def. Par. 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.

The programmable signals on X1 and J2 will be disabled with Q1 open, with the exception of the signals for “16 - Manual Bypass ON” and “26 - EPO”.
