Installing the Power-On Delay Relay
Due to the rate at which AC/DC power supplies reach their nominal supply voltage after application of power,
the relay contact of the timer should be installed between the output of the power supply and the power input
of the MCT control system components. This allows the power supply output voltage to reach its nominal value
prior to connecting the MCT to its output terminals.
In order to properly sense the loss of power, due to the hold-up times associated with AC/DC power supplies,
the time delay relay coil should be wired to the AC power source for the DC power supply of the MCT. This will
ensure that the MCT is turned off/on at the proper times and prevent malfunction that can be caused by rising
or falling voltage at the power supply output during power interruption.
NOTE:
It is recommended that the time delay-on relay be set for a period of 10-15 seconds to ensure proper
operation of the MCT control system.
