Relays

P111–Control Functions

The control function energizes the relay coils. When the instrument is at rest (no controls operating) the relay coils are de- energized.

P112–Relay ON Setpoint

Sets the process point at which the relay is tripped.

P113–Relay OFF Setpoint

Sets the process point at which the relay is reset.

P118–Relay Output Logic

Affects relay reaction. Reverses the logic (normally-open to normally-closed or vice versa).

P129–Relay Failsafe

Changes how individual relays react to a failsafe condition on the instrument.

Relay Wiring Test

P119–Relay Logic Test

Checks the application wiring by forcing a relay control function, such as a level alarm or pump control setpoint. Ensure all the relay programming and wiring works properly.

Please verify that ON and OFF respond correctly. Use P119 as a final test once all of the relay programming is done.

Relay Activation

The flexibility of the relay functions ensures that the MultiRanger can support relay wiring for different systems and applications. Use the following as a guide to the most common parameters.

Relay Setpoints and Functionality

[MR 100]: When a setpoint is reached, the corresponding action is taken. The setpoint can be an ON or OFF setpoint related to a process variable.

[MR 200]: The setpoint can be an ON or OFF setpoint related to a process variable, or a timed setpoint based on interval and duration.
