Parameters
Failsafe (P070 to P072)
P070 Failsafe Timer
The time for invalid measurements to elapse before Failsafe State activates.
Once activated, the Failsafe State initiates the following:
1. The material level is reported based on P071 Failsafe Material Level.
The unit responds to the new level as programmed (control and alarm relays
activate as defined by the programming).
Individual relays can have independent failsafe responses. See P129 Relay
Failsafe.
2. The appropriate error is displayed:
LOE for loss of echo from the transducer
Short for a shorted transducer cable
Open for a cut transducer cable
Error for all other problems
When modifying the preset value, set it short enough to protect the process but long
enough to avoid false alarms. Only use No Delay (0.0 Minutes) for testing.
P071 Failsafe Material Level
The material level reported when a Failsafe State is initiated.
Select the Failsafe Material Level based upon the relay operation required during failsafe
operation.
