Drawer Management
Presentation
The drawer management application is used to record and check the position of withdrawable drawers.
The monitoring from a remote controller using the communication network requires a communication interface module (IFM or IFE interface).
-
The cradle and the drawer applications cannot be configured together.
-
The drawer management application is not available for drawout MasterPacT MTZ circuit breakers equipped with EIFE interface.

Drawer Position Status
The drawer position status is defined from the status of the digital inputs I1, I2, and I3.
-
Drawer in connected position (I1=1, I2=0, I3=0)
-
Drawer in disconnected position (I1=0, I2=1, I3=0)
-
Drawer in test position (I1=0, I2=0, I3=1)

|
Disconnected |
Drawer is in disconnected position |
|
Test |
Drawer is in test position |
Drawer Position Counters
The drawer position counters are:
-
Drawer connected position counter
-
Drawer disconnected position counter
-
Drawer test position counter
A counter is linked to each drawer position state. The counter is incremented on each rising edge of the linked state.
The drawer position counters have the following properties:
-
The counters are saved in non-volatile memory to prevent a data loss if there is a power loss.
-
The counters are incremented from 0 to 65534.
-
The counters can be preset to any value from 0 to 65534 using the FDM121 display.
Application Events
The following event is generated by the application. For more information on IO module events, refer to Events and Alarms.

Drawer Position Discrepancy Alarm
The IO module detects any drawer position discrepancy and generates an alarm when the drawer position contacts indicate that the drawer is not in one of the possible positions, connected, disconnected, test, or none of the positions.
Recommended action: Check the status of the drawer position contacts, wiring to the IO module and the inputs of the IO module.
