Relays may be programmed as Standard Alarms or for Custom Relay operation.
For Standard Alarms
Standard AlarmsStandard Alarms
Standard Alarms (relays operate based on material level), select the Relay Set Up
(P100) desired and alter the Standard Alarm (P101 to P104) parameters as required,
before proceeding to Relay Failsafe (P129).
For Custom Relay operation, select the Relay Set Up (P100) which most closely matches
your requirements, and alter the Custom Relay Parameters (P110 to P113) as required,
before proceeding to Relay Failsafe.

Relay status during a measurement difficulty is dependent upon Failsafe
programming. (See Failsafe Parameters (P070 to P072) and Relay Failsafe (P129).
As preset, relay status is "held" at last known material levels until a valid
measurement is made.
Independently altered Standard Alarms (P101 to P104), Relay Allocation (P110),
Relay Function (P111) and Relay A / B Setpoints (P112/P113) are automatically
reset when a Relay Set Up value is altered.
