Installation Guide

Static Pressure Control

Besides VAV applications, the CSP-4702 can also act 

as a static pressure controller in such applications as 

AHU or RTU bypass control. It is not then connected 

to a thermostat. For information, see the 

CSP-4702

Troubleshooting

No Rotation

NOTE:

  For about 15 seconds after power is applied, 

no rotation occurs and one or both of the 

LEDs will flash.

• 

Check that the shaft moves freely. (Press and 

hold the gear disengagement lever and manually 

rotate the shaft.)

• 

Check wiring. (See Wiring Issues section below.)

• 

Check for a tripped circuit breaker to the 

transformer, for proper supply voltage from the 

transformer (or power supply), and for enough 

capacity (VA) for all connected devices. See their 

respective data sheets and 

Tips for Connecting 

24-Volt Power Application Note (AN0604D)

 

available on the KMC Controls web site.

• 

Check that the direction jumper is in the proper 

position. See 

Rotation Direction on page 2

.

• 

Check the polarity and level of the input signal 

from the thermostat.

Wrong Rotation Direction or Stroke Range

• 

Check the position of the direction jumper. See 

Rotation Direction on page 2

.

• 

Check the flow limits (on the controller and the 

thermostat). See 

Min. and Max. Flow Limits on 

page 3

.

• 

Check the adjustable stop position.

No Pressure Output Signal

• 

Check the wiring. (See Wiring Issues section 

below.)

• 

Check air flow and sensor. Tubing should be free 

of kinks and restrictions. Sensor must be oriented 

in the correct airflow direction.

Wiring Issues

• 

Check for correct wiring at the each device.

• 

Use a voltmeter and ohmmeter to check the 

terminals for expected values.

• 

See 

Tips for Connecting 24-Volt Power Applica-

tion Note (AN0604D)

.

NOTE:  Wiring must be adequate to avoid 

excessive voltage drop on long runs! Allow 

plenty of “cushion” in measurements. A 

meter may be too slow to register transient 

dips or peaks during startup.
