10 Configuring the control’s inputs and outputs
68 PHLOX II Ignition Control System
output frequency since at 50 Hz a period is 20 ms long and the delay time
therefore must in any case be longer than this value.
The following table provides an overview of possible errors:
Signal short circuit to earth
- Governor has detected a short circuit to earth.
only error message
Check wiring and connected loads.
Short circuit to supply voltage
- Governor has detected a short circuit to supply voltage.
only error message
Check wiring and connected loads.
Table 22: Possible errors for PWM outputs
The parameter
51x1 DOPWMx_HoldOrReset hold or reset error message
allows the user to configure whether the error message is to be reset when the error state
is no longer present. This applies comprehensively to all error messages during this out-
put.
10.5 Digital outputs
A digital output may be assigned to each measurement or indication value with value range
[0,1] in parameter list 2. In addition, for the output of error parameters it is possible to read
out single errors of an error state. To achieve this, single bits of an error state are selected
by means of a mask parameter to determine the specific errors. If more than one error bit is
selected, the output becomes active as soon as at least one error bit is set.
Several values may be assigned to each digital output (so called multiple allocation).
The values currently output are displayed by parameter 2851 DigitalOut1 and subsequent
parameters.
The parameter settings described in the following sections – in particular mul-
tiple allocation – can be achieved in an easy and comfortable way using a ded-
icated window of DcDesk 2000.
