Custom Timers and Intervals
This chapter describes how to create custom timers and intervals with the Configurator.
Timers and intervals let you control when and for how long a certain operation takes place.
For example, you can use a timer to delay a vent fan until the damper has had time to open, or
to delay the activation of compressors so that they do not all activate at once and overload the
system.
You can use an interval to change the language of announcements at certain times of day, or
to turn on a dedicated air handling system once a week for testing.
All timers are initially un-assigned. To enable a timer, edit the
Enable
column to make it
Y
.

Custom Timers
You can create a timer to delay activation of an output, limit the time an output is active, or
cause a delayed activation of additional outputs. You do this with the
Custom Timers
section
of the Configurator, and with advanced logic.
To make a custom timer you must:
•
Create the timer.
•
Create a trigger to start the timer using advanced logic.
•
Use the timer in an advanced logic equation to activate a zone.
•
Correlate the zone with the output.
Follow the instructions below to complete these steps.
8.1.1
Creating a custom timer
Create a custom timer
1. Select
Custom Timers
in the job tree on the left side of the Configurator window.
The list of custom timers appears on the right.
2. In the row for the next unassigned timer, double-click in the
Enable
column, and then
click
Y
in the pulldown menu.
3. Double-click in the
Duration
column, and then type the duration of the timer in seconds.
4. Double-click in the
Tag
column, and then type a name for the timer.
The Configurator gives each timer a number starting from 16.
Note:
As per UL 864 and UL 2572 only a setting of un-assigned is permissible.
