Rishabh RISH Master 3440 - 8.2 Limit Switch:

Divisors 100
CT secondary = 1A Max pulse rate 3600 pulses per 100Ah **
CT secondary = 5A Max pulse rate 720 pulses per 100Ah **
Divisors 1000
CT secondary = 1A Max pulse rate 3600 pulses per 1000Ah **
CT secondary = 5A Max pulse rate 720 pulses per 1000Ah **
Pulse duration 60 ms, 100 ms or 200 ms
**No. of Pulses per Ampere hour = Maximum Pulses / CT Ratio Where, CT Ratio =
(CT primary/ CT Secondary)
8.2 Limit Switch :
Limit switch can be used to monitor the measured parameter ( Ref.Table:2 )in relation
with to a set limit.
The limit switch can be congured in one of the four mode given below:-
1) Hi alarm & Relay Energized Relay..
2) Hi alarm & De-Energized Relay.
3) Lo alarm & Energized Relay.
4) Lo alarm & De-Energized Relay.
Limit switch has user selectable Trip point, Hysteresis, Energizing Delay & De-Energizing delay.
Hi Alarm:
Lo Alarm:
If Hi-Alarm Energized or Hi Alarm De-Energized option is selected then relay will get
energized or De-energized,if selected parameter is greater than or equal to trip point.
If Lo-Alarm Energized or Lo Alarm De-Energized option is selected then relay will get
energized or De-energized,if selected parameter is less than or equal to trip point.
