Hipulse - Single Phase ‘1+N’ UPS System

130 kVA - 110V

10.1 Remote Alarm Monitor

The Remote Alarm Monitor (RAM) Board can be used in conjunction with the AS400 Alarms Interface Board to display the UPS alarm and status information at a remote station to 100 meters from the UPS.

The RAM, which can be mounted either horizontally or vertically contains a mains- driven power supply for alarm LED annunciation and displays the following warnings:

state

 

 

 

Inverter ON

Green

ON

Normal operating condition indicating that the load is being supplied by the inverter.

 

 

 

This is not an 'alarm’ indicator.

 

 

 

 

Utility failure

Red

OFF

When lit, it indicates that the input bypass is out of tolerance or missing.

Battery low

Red

OFF

When lit, it indicates that the battery voltage is below minimum or that the battery

 

 

 

circuit breaker is open.

 

 

 

 

Bypass ON

Red

OFF

When lit, it indicates that the load is being fed from the bypass supply, possibly due

 

 

 

to a UPS failure.

Maintenance

Red

OFF

When lit, it indicates that the UPS has been selected to operate on the maintenance

 

 

 

bypass and load is unprotected.

 

 

 

 

Alarm

Red

OFF

This is a ‘common alarm’ and is lit when any of the red leds described above are lit

 

 

 

Table A

An audible warning accompanies any of the above alarm conditions. This is, however, subject to a short time delay when activated in conjunction with the 'Utility Failure' and 'Bypass ON' alarms, to prevent the warning being activated by transient conditions. Pressing the 'reset' push-button cancels the audible warning but the alarm indications remain until the conditions is rectified.

10.1.1RAM Connections

Power Supply

The RAM contains a single-phase 220-240 V AC mains-driven power supply. Power is applied through a standard three-pin mains connector located in the RAM back panel (plug provided) -use 3-core 0.5 mm cable (minimum). The supply is rated at approximately 4 Watts and fused at 1 A.

It is advised that the power supply is taken from the UPS output, otherwise in the event of a mains failure the RAM may be inoperative.

Alarm connections

A 9 pin D-type connector with solder points is provided with the RAM. This connector fits into the 9 pin socket on the back of the RAM and should be cabled to the Interface Board # 10020112003 fitted to the UPS, using 9 core, 0.22 mm. (minimum) shielded cable as shown. The maximum recommended distance is 100 meters.

Note: Operation of the RAM indicators, is achieved by feeding a voltage across the module Alarm Board relay contacts. No other connections should be made across the relay contacts used.
