Each instrument is provided with dual displays and status indicators as shown in Figure

1.3 Control
The instrument can be programmed for on-off, time proportioning, or current
proportioning control implementations depending on the model number. A second
control output is an available option. Proportional control implementations are provided
with fully programmable PID parameters.

Alarm type may be set as Process Direct or Reverse (high or low), Deviation Direct or
Reverse (above or below setpoint), Deviation Band Type (closed or open within band),
or Loop Reverse or Direct. Alarm status is indicated by LED. An Alarm Inhibit is
provided to prevent, when activated, unwanted alarms during power-up.
