4.3.14 Timer Set Up Group
Introduction
The timer option allows you to configure a timeout period and to select the timer start by either the
keyboard (Increment or Decrement key) or Alarm 1. The optional digital input can also be configured to
the start the timer. The timer display is selectable as either “time remaining” or “elapsed time”.
Alarm 2 is activated at the end of the timeout period. When the timer is enabled, it has exclusive control of
the Alarm 2 relay; any previous Alarm 2 configuration is ignored. At timeout, the timer is ready to be
activated again by whatever action has been configured. Relay 2 will remain energized until the timer is
reset.
See Subsection 4.5.2.7 for operation of timer.
