RELAY
OPERATION

Batch control
Automatic (non-latching)

1

Sampling
Off (disable unused relays and enable Interlock feature)
Manual on/off control mode
Secondary Functions

2

Pump alternation control (2 to 8 relays)
Latching (requires manual acknowledge)

RELAY RESET

User selectable via front panel buttons, digital inputs, or PC

1. Automatic reset only (non-latching), when the input

passes the reset point or total is reset to zero.

2. Automatic + manual reset at any time (non-latching)
3. Manual reset only, at any time (latching)
4. Manual reset only after alarm condition has cleared (L)

Note: Digital inputs may be assigned to acknowledge relays
programmed for manual reset. It is not recommended to
change the functions of front panel buttons to manual reset.

ALARM TIME
DELAY

0 to 999.9 seconds, on & off relay time delays
Programmable and independent for each relay.

FAIL-SAFE
OPERATION

Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition.

In case of power failure, relay will go to alarm state.

ALARM AUTO
INITIALIZATION

When power is applied to the controller, relays will reflect
the state of the input to the controller.

1. Alarms are active only when the batch is running.
2. These functions are not functional when the unit is being used as a batch

controller with total set to yes.
