Control Inputs
Acknowledge firing speed via terminal 62
Parameter 196
Firing speed by
Term. 62 ON
Firing speed reached via terminal 62 ON/OFF
OFF..............This terminal is used as an alarm input.
ON................Configuring the starting sequence logic:
If
Parameter 191 is configured to "E", the discrete input utilizes
“N.O.” contacts and the starter disengages when the status of this
discrete input becomes TRUE. Once the delayed engine monitoring
time has expired, the discrete input changes to "N.C." logic internally
even though "N.O." logic is still programmed This permits the con-
troller to generate an alarm condition in the event of a voltage loss
(including a configured time delay). This input will operate on the
inverse of this principle as well. If
Parameter 191 is configured to
"D", the discrete input utilizes "N.C." logic to disengage the starter in
the event of a voltage loss. Once the delayed engine monitoring has
expired, the discrete input changes to "N.O." logic internally even
though "N.C." logic is still programmed and will initiate an alarm as
soon as voltage is applied.
Block operation mode selector switch via terminal 63
Parameter 197
Op.mode blocked
by Ter.63 ON
Disabling the change of the mode using terminal 63 ON/OFF
OFF..............This terminal is used as an alarm input.
ON................Terminal 63 is used as control input.
If terminal 63 is energized, the operation mode cannot be changed
using the pushbuttons on the face of the control unit.
If this input is configured as control input and energized, it is possible for units with Option A2 from version
1.0700 to select the operation mode externally using the control inputs at terminals 127 and 128. The functional-
ity is described in the following table:
Operation

(terminal 63)
Input
STOP
(terminal 127)
Input
AUTOMATIC
(terminal 128)
Function
de-energized not applicable not applicable The operation mode can be selected using the buttons at the front of
the GCP. (The terminals 127/128 have no effect.)
energized de-energized de-energized No change in operation mode. After connecting the supply voltage,
the unit is in STOP operation mode. The operation mode selection
buttons at the front of the GCP are blocked.
energized energized de-energized The STOP operation mode is activated. After connecting the supply
voltage, the unit is in STOP operation mode. The operation mode se-
lection buttons at the front of the GCP are blocked.
energized de-energized energized The AUTOMATIC operation mode is activated. After connecting the
supply voltage, the unit changes to AUTOMATIC operation mode via
STOP.
energized energized energized The STOP operation mode is activated. After connecting the supply
voltage, the unit is in STOP operation mode. The operation mode se-
lection buttons at the front of the GCP are blocked.
