6. Switch Setting
The AKM345 GEN3 can be equipped with 2, 4, or 6 Form C contact switches. These switches can be used for
alarming and control of cooling equipment.
Each switch is independently adjustable across the dial range. Switching accuracy is ±3% of the dial range. Switches
are calibrated at the factory.
As an option, the switches can be specified for high DC current applications or with gold contacts for intrinsic
environments.
Qualitrol does not recommend setting more than 2 switches at the same setpoint, as this can reduce device
accuracy.
6.1 Switch Setpoint Adjustment
The procedure for adjusting each switch setpoint is as follows:
Step 1)
Open the unit as noted in section
Step 2)
Loosen the screw on the red pointer.
Switch Adjustment Locking Screw
Step 3)
Hold the screw in position and rotate the scale drum until the red pointer indicates the desired contact
point on the scale.
Step 4)
Tighten the screw in this position.
Step 5)
Check that contact is obtained by pulling downward on the tab to the right side of the switch stack so
that the pointer of the temperature gauge moves towards the higher values on the scale. The tab shall
never be pushed upward, this can cause the unit to be out of calibration. When checking the
instrument, it must be placed in a vertical position.
