6.6 Indication of ESM/Fire Mode
6.6.1 BOP indication of ESM/Fire Mode
Once ESM has been activated by closing the DIN, the display on the BOP will flash
every 6 seconds
ES and alternate with the value set in P0005.
This will not appear on the AOP.
6.6.2 Relay output indication of ESM/Fire Mode
If a relay is required to change state once ESM is activated, the same value that is
used to activate P1270 can be used for the relay.
For example, if DIN2 is used to activate ESM, then P1270 will be set with the value
722.1. This value will also be used to set the relay (e.g. using relay 2):
P732 in000= 722.1
Digital Input used for ESM/Fire Mode
DIN1 DIN2 DIN3 DIN4 DIN5 DIN6
Relay 1
P0731in000= 722.0 722.1 722.2 722.3 722.4 722.5
Relay 2
P0732in000= 722.0 722.1 722.2 722.3 722.4 722.5
Note: This only works when the responding DIN is set to «99» (BICO). Please take
note of the indexes of the DINs.
6.6.3 Fault Handling in ESM/Fire Mode
The SED2 is designed to ignore all faults and warnings when ESM has been acti-
vated except ‘hard faults’.
Hard faults are determined as:
F0001: Short-circuit, phase to phase and ground faults typically seen within the
SED2.
F0002/F0003: Overvoltage and undervoltage conditions will cause the drive to trip
F0023: The disconnection of the motor while the SED2 is running
In the event any of these faults occur, the SED2 will shut down with an OFF2 stop
(coast to stop) and attempt a fault acknowledge and automatic restart.
It will attempt this process indefinitely, or until the SED2 is destroyed.
6.6.4 Automatic re-start in ESM/Fire Mode
When ESM has been activated and enabled (closing the DIN assigned for ESM),
the setting within P1210 (automatic restart) will internally change to setting 6.
Setting 6 will allow automatically restart after mains brown-out, mains black-out or
fault. The number of restarts will be indefinite.
