STAGE 1 OPEN RUN TIMER
The open run timer establishes the period of
time that the actuator motor operates when it
receives the command to open an air inlet
baffle board or air inlet curtain.
The open run timer is adjusted in 1 second
increments from a minimum setting of 1 second
to a maximum setting of 1 minute 59 seconds.
Adjusting the open run timer:
•
rotate the Selector dial to position (10),
•
rotate the Adjustor dial counterclockwise to
decrease the setting, and clockwise to
increase it.
The open run timer setting is displayed on the
CPS-2M.
OPEN
Example:
The open run timer is set to 30 seconds. When the
control determines that the air inlet must open, the com-
mand to the motor is sent after the delay set by
secondary function (2) has expired. The actuator motor
will operate for 30 seconds before stopping.
