Hired-Hand Farm Hand Series: POWER VENT INLET - Manual (Page 10)

Part No. 4801-0149 Rev 1-01 Farm Hand Power Vent 8
8.2.11. P63 = Cycle Pressure Alarm Limit (Ramping Model Only)
This setting determines the pressure limit the cycle alarm looks for. For example, If you
set this value to .20, and the controller never sees a pressure spike of at least .20”w.c.
during it’s cycle time, the controller will sound the alarm.
8.2.12. PS1 = Calibrate Sensor 1
The sensor temperature reading is alternately displayed along with the parameter number.
You should never attempt to calibrate a sensor more than 8 degrees. If you have a setting
that far out of range, it indicates that there is a problem that should be corrected.
This reading can be changed by pressing the + or - button until the desired reading is
displayed.
Remember that in order to properly calibrate sensors you need two persons. One at the
controller, and one with a trusted thermometer actually at the sensor.
Press the mode button to return the controller to automatic operation.
9. Error Codes
E2 = Cycle Error
E4 = High Pressure Error
E6 = Cycle Error and High Pressure Error
E8 = Low Pressure Error
E10 = Cycle Error and Low Pressure Error
E12 = Low Pressure and High Pressure Error
E14 = Cycle Pressure, Low Pressure, and High Pressure Error
As long as the error condition exists, the alarm will sound. If the error condition clears (pressure drops
below high pressure alarm setpoint, for example) the controller will stop sounding the alarm, but record the
error and continue to display the error in the display until the controller is reset by disconnecting power to
the controller and reconnecting power to the controller.
10. Maintenance
There are few items on the controller that require maintenance. However you should check the calibration
of your sensors once per quarter to be sure of accurate readings. Also, inspect any wiring associated with
the vent system and replace any wires with worn, or cracked insulation.
