Connections And Manual Override Board - Data Aire dap4 User Manual

Manual Override Switches
For testing, during start-up and in the event of emergency, each Data Aire gForce unit is
provided with manual override slide switches. There are seven slide switches, one for
each of the following functions:
Water Valve
Humidifier
Cool 2
Blower
Simply slide the manual switches to energize the load and, the display module will
indicate "Manual Override". All automatic functions of the controller are disabled and all
desired functions must be performed with the manual override switches.
The fan speed of the EC (Electronically Commutated) motor can be adjusted from 0 – 10
volts by adjusting the potentiometer at the left of the Fan Speed switch. The fan will turn
10% for each volt adjustment. One volt equals 10%. At ten volts the motor is at full speed.
Warning: Do not leave the unit in manual override. Slide the switches to the OFF
position when completing testing and/or start-up. An alarm will be activated if any switch
is left in the ON position.
