Command Close Coil Serial Communications
The Command Close Coil is actuated either by applying a signal voltage to the A11 terminal via external
contact or optional breaker electrical close pushbutton, or it can be commanded through a properly
configured EntelliGuard trip unit via serial communications. Note that the Command Close Coil must be
continuously powered at A9/A10 to receive trip unit commands.
Figure 2 shows the electrical interconnection between the trip unit and the Command Close Coil accessory.
The trip unit must have an auxiliary DC supply to use serial communications functions.
To command the close coil remotely using Modbus, send a Coil ON command (Modbus Function Code 05
ON) to register 111. The command will remain in effect until it is turned OFF.
To turn off the command, send a COIL OFF command (Modbus Function Code 05 OFF) to register 111.
Note that the remote command input must be set to OFF and the local command inputs must be OFF
before the close coil can be retriggered with a new command.
Refer to DEH-4567 EntelliGuard Trip Unit Instruction for more details.
