How Electrical On-Delay Staging Relays Work

staging-relay
By
Summary: This section will cover the use of relays that are sometimes needed to control special device loads such as Air Conditioners and other high demand equipment from starting at the same time.

Problem Solvers for Air Conditioners - Energy Savers for Large Electrical Loads
  This method will help prevent nuisance tripping of sub-feed circuit breakers and reduce the electrical demand on your utility service which could lead to much higher energy bills.

Introduction:
ICM100/101 DELAY ON MAKE
• 3 or 5 minute fixed
• Works with anticipator thermostats


MODE OF OPERATION:
When power is applied to the input, the
time delays begins. After the time delay is
complete, the load energizes and remains
energized as long as power is applied.
The control is reset by removing power
during or after the time delay period.




INSTALLATION

1. Disconnect power.

2. Connect terminals in series with the
starting device as shown in the wiring
diagram below.

3. Reapply power, check operation.

4. Trickle current bypass resistor
T1 to T3 <1K ohm.

Electrical Tip

The Safest Way to Test Electrical Devices and Identify Electric Wiring!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
