Operating Instructions
1-Q-EC Amplifier DEC Module 50/5
April 2015 Edition / document number 1094861_PDF_E - 05 / subject to change
5.2.3 Status indication «Ready»
The «Ready» output can be used to report the state of operational readiness
or a fault condition to a master control unit.
In normal cases (no fault) the output is switched to 5V.
Ready (no fault)
5 V
In case of a fault the output is switched to Ground.
Fault (not ready)
0 V (Gnd)
Possible reasons for a fault message:
Ö
Undervoltage
Fault message occurs in case supply vV
CC
< 6 VDC.
To reset the fault condition the amplifier must be disabled and the supply
vV
CC
must be higher than 6 VDC.
Ö
Overvoltage
Fault message occurs in case supply vV
CC
> 56 VDC.
To reset the fault condition the amplifier must be disabled and the supply
vV
CC
must be lower than 54 VDC.
Ö
Thermal overload
Fault message occurs in case
power stage temperature is > 100°C.
To reset the fault condition the amplifier must be disabled and the power
stage temperature must fall below 80°C
Ö
Invalid Hall sensor signals
The amplifier recognizes invalid conditions at the Hall sensor inputs.
To reset the fault condition the amplifier must be disabled and the Hall
sensors must be wired correctly.
The output «Ready» is protected against continuous short circuit.
