P102 Low Alarm
Sets the low alarm setpoint for relay selected, relays 1 to 5 (P100 - 01 to – 05). (f=20)
Enter the value in % of full scale
Note:
Differential Speed (f = 90)
For differential speed functions, P100 = 10, this parameter sets the low alarm setpoint for
the relay selected, relays 1 to 5 (P100 -01 to -05).
P107 Relay Alarms
Sets the alarm mode for the relay selected, relays 1 to 5 (P100 - 01 to - 05.
Entry:
1 = high and low
2 = high only
3 = low only
Note:
P117 Relay Dead Band
Sets the dead band for the relay selected, relays 1 to 5 (P100 - 01 to – 05). The dead band
prevents relay chatter due to fluctuations at the high or low setpoint. (
Enter the value in % of full scale, or for deviation alarm enter % of setpoint.
Note:
P118 Relay Logic
Sets the logic applied to relays to determine their open or closed state.
Power Failure
The relays on the BW500 default to normally open under power loss.
Normal Operation
In software, all relays are programmed the same way; with ON setpoints always
indicating relay action. This parameter allows the reversal of the operation. Normally,
P118 = 2 for each relay.
