4 Faults and alarms
4.2 List of faults and alarms
Remedy: - check binector input p3866[0...7] and the wiring from terminal X21.4 ("booksize" format) or X21.5 ("chassis" format).
- reduce the number of braking operations.
- check the 24 V power supply of the component.
- check for a ground fault or short circuit.
- replace the component if necessary.
Reaction upon F: NONE (OFF2)
Acknowl. upon F: IMMEDIATELY
A06901 Braking Module: Pre-alarm I2t shutdown
Message value: %1
Message class: Braking Module faulted (14)
Drive object: B_INF
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The Braking Module "Booksize" format signals "Pre-alarm I2t shutdown" via terminal X21.3.
This signal is wired to a system digital input and correspondingly interconnected using binector input p3865[0...7].
Note:
This function is not supported for the "chassis" format.
Remedy: - reduce the number of braking operations.
- check binector input p3865[0...7] and the wiring from terminal X21.3 of the particular Braking Module.
A06904 (N) Braking Module internal is inhibited
Message value: %1
Message class: Braking Module faulted (14)
Drive object: B_INF
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The internal Braking Module was inhibited via binector input p3680 = 1 signal.
In the inhibited state, energy cannot be dissipated using the braking resistor.
See also: p3680 (Braking Module internal inhibit)
Remedy: Release the internal Braking Module (BI: p3680 = 0 signal).
Reaction upon N: NONE
Acknowl. upon N: NONE
A06905 Braking Module internal I2t shutdown alarm
Message value: %1
Message class: Braking Module faulted (14)
Drive object: B_INF
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The internal Braking Module outputs an alarm due to the high I2t value.
80% of the maximum switch-on duration of the braking resistor has been reached.
Note:
This message is also displayed via BO: p3685.
See also: r3685 (Digital Braking Module: Pre-alarm I2t shutdown)
Remedy: Reduce the number of braking operations.
