Test For Shutdown; Replacement Time Delay Relay Assemblies - Johnson Controls Penn P28 Series Manual

To increase the cut-out pressure, turn the
Adjusting Disk counterclockwise. To decrease,
turn clockwise.
To raise the pressure differential, turn the
Adjusting Disk (see Figure 2) to the left when
viewing the front of the control. Turn the adjusting
disk to the right to lower the pressure differential.
T
est for Shutdown
Immediately after installing, and at regular intervals
thereafter, the time delay relay should be tested to
verify that all circuits are operating correctly.
!
WARNING: Shock hazard. Disconnect
power from the control before
testing for shutdown to avoid
electrical shock or damage to
the equipment.
To test for shutdown:
1. Remove power from the control and remove the
control cover.
2. Connect a jumper between Terminals 1 and 2.
See Figure 3 for terminal locations.
Note: If the control is mounted on a condensing
unit where air from auxiliary equipment
(blowers or fans) may strike the control,
the control cover should be replaced
before proceeding to Step 3.
