Installation
Mounting Instructions
Mount the control enclosure in a convenient,
accessible location that provides the best visual
advantage. Mount the enclosure to a wall or
column with little or no vibration and away from
static discharges that could damage components.
Pneumatic Sensor Line Connection
To get reliable signals to the sensors, the pneumatic
sensor lines should not exceed 250-ft. Excess length
can weaken the signal to the point that they are not
readable. Included with the Checker board is 35-ft
of each of the pneumatic lines. Contact Donaldson
if the sensor lines must be longer than 250-ft.
Thermistor
Connect the temperature sensor to the appropriate
connection point on the Checker board using
grounded, shielded, twisted pair wire (50-ft
included), in metal conduit. Locate the thermistor
and thermowell inside the clean-air chamber.
Current Sensor Wiring
The leads that connect the current sensor board to
the main board should be shielded twisted pair
wires (two 50-ft lengths included) enclosed in metal
conduit.
