Meaning of the REC 37.100A2 system
Internal error
Internal error: no valid load checking device
Internal error
Fuel/air checking error: Calculation position in
modulation
Invalid load
Curve points not defined
Special position not defined
Standby position
Pre-purging position
Post-purging position
Ignition position
Fuel/air internal checking error:
Fuel/air internal checking error: multistep calculation
position
Position calculation, invalid stage load
Position calculation, stage curve points not defined
Fuel/air ratio internal checking error: cyclical data
check
Check synchronisation data, different current load
Check synchronisation data, different target load
Check synchronisation data, different target positions
Check synchronisation data, different positions reached
Fuel/air internal checking error:
VSD control range limit
Lower control range limit
Upper control range limit
Interruption in speed limit input
Error during VSD speed standardisation
Standardisation time-out (the descent time of the VSD train
is too long)
Logging of the standardised speed not successful
Speed sensor circuit open
58
Recommended measures
Carry out a reset; if the error arises repeatedly, replace the
control box
Carry out a reset; if the error arises repeatedly, replace the
control box
Carry out a reset; if the error arises repeatedly, replace the
control box
No valid load
Adjust the curve points of all the actuators
Set the standby position of all the servomotors used
Set the pre-purging position of all the servomotors used
Set the post-purging position of all the servomotors used
Set the ignition position of all the servomotors used
Carry out a reset; if the error arises repeatedly, replace the
control box
No valid load
Adjust the curve points of all the servomotors
May be caused by different standardisation speeds (for
example following the resetting of the data set) when the VSD
is active -> perform the standardisation again and check the
regulation of the fuel/air ratio.
Carry out a reset; if the error arises repeatedly, replace the
control box
The standard unit could not correct the speed difference and
has reached a limit in the control range.
1. The base unit is not standardised for this motor
----> repeat the standardisation.
WARNING!
check the settings of the air/fuel ratio control!
2. The VSD train times are not shorter than those of the
standard unit (parameters 522, 523).
3. The VSD characteristic is not linear. The VSD voltage input
configuration must correspond with that of the standard unit
(parameter 645).
4.The VSD does not follow the changes of the standard unit
quickly enough. Check the VSD settings (input filter, slide
compensation, different latent speeds).
The VSD speed was too high
The VSD speed was too low
Excessive electromagnetic interference on the sensor line ->
improve the EMC
Time-out at the end of the standardisation, during deceleration
of VSD
1.The VSD train times are not shorter than those of the
standard unit (parameter: 523)
Error during the logging of the standardised speed ---> block
the standard unit, reset it and repeat the standardisation
The standard unit does not receive pulses from the speed
sensor:
1. The motor does not rotate.
2. The speed sensor is not connected.
3. The speed sensor is not activated by the sensor disc (check
the distance)
