FOR AIR PROVING ON BY-PASS OR FLOW-THRU HUMIDIFIER
INSTALLATION 1. Ensure power conductor to be monitored is disconnected and locked out from the power source!
HUMIDIFIER MOTOR OR SOLENOID
2. Install the removable mounting bracket to the back of the electrical enclosure, if desired. C
3. Snap the split core around the conductor to be monitored and close until the core snaps shut. NOTES: To monitor current under .15 Amp see installation note. 4. Connect current switch output to switched load. (See diagrams to the right).

MODEL T40-VA 24 VAC TRANSFORMER HUMIDISTAT SOURCE
5. Snap the APD back into the mounting bracket or allow the APD to hang on the conductor. Note: Contacts are solid state and work just like dry contacts. When the switch is closed 1 Ohm is present. When the switch is open more than 1 Megohm is present.

6. Reconnect power.
MODEL ND-ESR / URD-ESR POWER OPEN / SPRING CLOSE
INSTALLATION NOTES For currents less than .15 Amp: To provide adequate current, wrap the conductor through the center hole and around the sensor body to produce multiple passes and increase measured current. Measured current = Actual current times the number of passes.
