Relays

Three relays are provided which are activated on alarm exceedan-

ce if so programmed.

They are designated as K1, K2, and K3.

Programming the Relays

Relay operation is defined by the setup parameters:

1. Which limit value controls which relay.

2. Latching or Non-Latching Mode.

3. Energized or de-energized Operation.

4. Control a relay by combining several limit values using a

logical OR or AND statement.

Comment to 1.

Limit value exceedances can be configured as single events or

grouped events.

A configuration that is commonly used is, lim_1A and lim_1B con-

trol relay K1, and lim_2A and lim_2B control relay K2.

Comment to 2.

Latching Mode

The relay remains latched (tripped) until it is reset using the control

panel, reset switch, or via the remote interface.

Non-Latching Mode

The relay is automatically reset when the measured value drops

below the limit value.

Comment to 3.

This choice depends on the user's philosophy. What is important

though, is preventing a false relay trip if power to the VIBROCON-

TROL 1100 is disconnected.
