IMPORTANT!
WARNING!
IMPORTANT!
What happens during the Calibration?
−
Load Monitoring is switched off.
−
The impedance limits are determined for measurements made
with Pilot Signals and Program during operation.
−
The minimum signal levels for the Pilot Signals are determined;
these are necessary to ensure exact measurement results.
−
The display values for the last impedance error ('Last-Err Z') are
set to 0.0 Ohms.
Possible error messages during the Calibration
Cancelled by User!
The user has interrupted the Calibration either by pushing the
Encoder or remotely.
Current too low
The level was increased to the maximum value, but the minimum
current wasn't reached. In most cases this error message will be
displayed when a loudspeaker is not connected or there is a faulty
cable.
Current too high
The maximum current was exceeded at minimum level. In most
cases this error message will be displayed when a short circuit in
the cable or connector has occurred.
Power is off
The E- PAC is in Standby mode and an adjustment is not possible.
Remote via RIB
Load Monitoring adjustment via RIB
For safety reasons the Calibration is locked. To enable Calibration
the following procedure should be followed:
−
Switch on Load Monitoring (set 'Enable Bit')
−
Switch off Load Monitoring (reset 'Enable Bit')
−
Calibrate (set 'Calib-Bit')
Notes:
−
It is strongly recommended to protect the Calbration function in
ROPE by means of the Confirm dialog!
−
If the Calibration was successful, reset the 'Calib-Bit' in the
E-PAC.
−
If the Calibration was not successful, reset the 'Calib-Bit' in the
E-PAC again and set one or more ImpErr-Bits for 2 seconds.
−
If the user resets the 'Calib-Bit' during Calibration then the
process is cancelled.
Reset of impedance errors
To reset error indications either:
−
Power Off/On at the device or remotely.
−
Switching the Load Monitoring Off/On at the device or
remotely.
−
Setting the 'ImpErr-Bits' remotely.
