FUNCTION DESIGNATION OPERATION
Level LL, L, H, or HH Similar to Standard Alarms but with Relay A/B Setpoints
In Bounds b1 or b2 * Alarms when level is between the Relay A/B Setpoints
Out of Bounds b1 or b2 * Alarms when level is not between the Relay A/B Setpoints
Rate r1 or r2 * Level rate of change alarm with Relay A/B Setpoints
Temperature Not applicable Alarm is activated by independent Relay A/B Setpoints
LOE Not applicable Relay de-energizes in the event of Failsafe timer (P700) expiry
Cable fault Not applicable Relay de-energizes under transducer short or opened condition
Pump Not applicable With independent Relay A/B Setpoints
Timed Not applicable Based on Relay “duration/interval” Setpoints (P114/115)
* The Relay Designation is not displayed but is included in the BIC-II (if used) data message.
Note:
When the Relay Function is altered, affected Alarm Parameters (P101 to P104)
display “ch” (changed) when accessed. Use the Relay A/B Setpoints (P112/P113)
instead.
To reset the Relay Function to use Standard Alarms, enter the desired Relay Set Up
(P100).
Values:
0 = off (relay always de-energized)
1 = level alarm (preset)
2 = in bounds alarm
3 = out of bounds alarm
4 = rate of change alarm
5 = temperature alarm
6 = LOE alarm (Relay A/B Setpoints are not applicable)
7 = transducer cable fault alarm
50 = pump control (non-sequenced)
60 = timed activation based on “duration” and “interval” setpoints
Independent Relay Setpoints
Relay A and B Setpoint values set the critical points (based on the Relay
Function) where, in the Run mode ...
1. Relay status indicators are switched “ON” and “OFF”
2. Alarm Indicators (if programmed) are switched “ON” or “OFF”
3. Relays are “energized” and “de-energized”
For most Relay Functions, setpoint values represent sludge levels, entered in
Units (P005) or percent of Span (P007) as referenced to Empty (P006).
Temperature alarm values are entered in degrees Celsius (°C).
Note:
Rate alarms are entered in Units / minute or percent of Span per minute. A
positive value is entered for a filling rate alarm; negative for emptying.
