Differential Speed (f = 110)
For differential speed functions, P100 = 10, this parameter sets the high alarm setpoint for
the relay selected; relays 1 to 5 (P100 -01 to -05).
P102 Low Alarm
Sets the low alarm setpoint for relay selected, BW500: relays 1 to 5 (P100 – 01 to – 05),
BW500/L: relays 1 and 2 (P100 – 01 to – 02) (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; BW500: relays 1 to 5 (P100 -01 to -05).
P107 Relay Alarms
Sets the alarm mode for the relay selected; BW500: relays 1 to 5 (P100 -01 to -05); BW500/
L: relays 1 and 2 (P100 -01 to -02).
Entry:
1 = high and low
2 = high only
3 = low only
Note:
P117 Relay Dead Band
Sets the dead band for the relay selected; BW500: relays 1 to 5 (P100 -01 to -05); BW500/
L: relays 1 and 2 (P100 -01 to -02). 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, range is 1 to
10 %.
