6. Turn the Minimum Position Potentiometer fully CW.
The actuator should drive fully open.
7. Remove the jumper from TR and N. The actuator
should drive fully closed.
8. Return EconoMi$er IV settings and wiring to normal
after completing troubleshooting.
Supply--Air Sensor Input
To check supply--air sensor input:
1. Make sure EconoMi$er IV preparation procedure
has been performed.
2. Set the Enthalpy potentiometer to A. The Free Cool
LED turns on. The actuator should drive to between
20 and 80% open.
3. Remove the 5.6 kilo--ohm resistor and jumper T to
T1. The actuator should drive fully open.
4. Remove the jumper across T and T1. The actuator
should drive fully closed.
5. Return EconoMi$er IV settings and wiring to normal
after completing troubleshooting.
EconoMi$er IV Troubleshooting Completion
This procedure is used to return the EconoMi$er IV to
operation. No troubleshooting or testing is done by
performing the following procedure.
1. Disconnect power at TR and TR1.
2. Set enthalpy potentiometer to previous setting.
3. Set DCV maximum position potentiometer to previ-
ous setting.
4. Set minimum position, DCV setpoint, and exhaust
potentiometers to previous settings.
5. Remove 620--ohm resistor from terminals SR and +.
6. Remove 1.2 kilo--ohm checkout resistor from ter-
minals SO and +. If used, reconnect sensor from ter-
minals SO and +.
7. Remove jumper from TR to N.
8. Remove jumper from TR to 1.
9. Remove 5.6 kilo--ohm resistor from T and T1. Re-
connect wires at T and T1.
10. Remove jumper from P to P1. Reconnect device at P
and P1.
11. Apply 24 VAC power to terminals TR and TR1.
