Milltronics AIRANGER DPL PLUS - Bound Alarm Hysterisis; Relay a Setpoint; Relay B Setpoint; Relay Failsafe

P112 RELAY A SETPOINT
Enter the critical point for the desired action to occur (based on the Relay Function selected).
values: -999 to 9999
Relay A/B Setpoint values cannot be exactly equal.
P113 RELAY B SETPOINT
Enter the critical point for the desired action to occur (based on the Relay Function selected).
values: -999 to 9999
P 116 BOUND ALARM HYSTERISIS
For ‘in bounds’ and ‘out of bounds’
Relay Functions (P111 = 2 and 3 respectively),
a hysterisis or dead band prevents relay
chatter due to material level fluctuations
at the upper or lower setpoint.
Enter hysterisis in % of span or
units of P005. (Factory set at 2%).
The hysterisis value is applied
above and below the upper
and lower bound setpoints.
P129 RELAY FAILSAFE
Use this feature for relay failsafe operation independent from the Failsafe Material Level (P070).
When accessed, the Parameter Type display changes to the Relay symbol and the Point
Number display changes to the Relay Number (corresponding to the DPL+ terminals)
Select: "OFF" to have the relay respond to the Failsafe Material Level (P071).
"HOLd to hold the relay at the "last known" state until normal operation resumes,
"dE" to have the relay de-energize immediately, or
"En" to have the relay energize immediately,
When the Relay Function (P111) is set for:
a) "alarm" (any option other than "pump"), this feature is preset to "OFF".
b) "pump", this feature is preset to "dE".
To select an independent Relay Failsafe option value:
1. , to display to the Auxiliary Function symbol,
2. or , to scroll access the failsafe options.
3. , with the desired option displayed.
values: "OFF"
"HOLd"
