7.4.3 X21EP terminals/temperature sensor
Overview
A temperature sensor and the signal cable for the Enable Pulses (EP) function are connected at
the X21interface. The temperature sensor terminals are used to perform an external
temperature measurement.
The plug-in terminals are included in the Terminal Kit of the Smart Line Module.
Requirement
Note
Terminals X21.3and X21.4
Operation of the Line Module can only be enabled if the "1" signal is applied at the EP terminals.
If the "0" signal is applied at the EP terminals, pulse inhibit is enabled. As a consequence, energy
recovery is disabled and the bypass relays drop out. The DC link remains charged if the Line
Module is not isolated from the line supply in this process, for example because there is no main
contactor present.
