Relay reaction
The way in which relay programming reacts to the failsafe level depends on P129 Relay
Failsafe (page 48). By default:
• Alarm relays have P129 = OFF and so react to the Failsafe Material Level.
• Control relays have P129 = dE and so de-energize the relay when the unit enters
Failsafe mode regardless of the Failsafe Material Level.
P072 Failsafe Level Advance
Sets the speed the AiRanger DPL Plus advances to and returns from the Failsafe Material
Level.

Relays (P100 to P119)

The AiRanger DPL Plus has four relays (or digital outputs) used to control devices and
alarms. While the number of devices is limited by the relays, all control functions are
accessible through software and each parameter is indexed to the relays.
The AiRanger DPL Plus makes standard application programming easier by providing an
extensive list of presets in P100 (Preset Applications).
Standard alarms are set from P101 to P104. In the RUN mode, when the material level:
• rises to a High or High High Alarm value, the associated Alarm and Relay Status
indicators are displayed and the allocated relay(s) de-energize.
• falls 5% of Span (P007) below the High or High High Alarm value, the associated
Alarm and Relay Status indicators extinguish, and the allocated relay(s) energize.
• falls below the Low or Low Low Alarm value, the associated Alarm and Relay Status
indicators are displayed and the allocated relay(s) de-energize.
• rises 5% of Span (P007) above the Low and Low Low Alarm value, the associated
Alarm and Relay Status indicators extinguish, and the allocated relay(s) energize.
Note:
Enter all standard alarm material level values in Units (P005) or percent of
Span (P007) as referenced to Empty (P006).
