7 Setpoint adjusters

Digital Governor Basic System PANDAROS III
On request, the potentiometers, as specified under 6.1. and 6.2. can be supplied with
analogue adjustment knob with lock in place of the standard rotating knob. In this case,
ordering specification is SW..-..-m.
Likewise, a clamping fixture can be installed instead of the knob. The ordering
specification will then be SW ..-..-k.
7.3
Setpoint value adjustment by current signal
For the speed setpoint value a current signal of 4 – 20 mA can be directly connected to the
control unit. If the signal fails, the governor will adjust minimum speed according to the
4 mA value or use a pre-programmed substitute value.
7.4
Digital presetting of setpoint values
On condition that the governor is configured correctly, a digital setpoint source is possible
directly with two switch inputs (increase/decrease speed), e.g. digital synchronizing
manually or with PLC.
7.5
Setpoint value adjustment by pedal
This unit is basically an angular position transducer that translates gas pedal positions into
a proportional current or voltage for 0 - 45° rotational displacement. The resulting output
can be used for speed setting. For more information refer to manual E 83 005 - e.
7.6
Pneumatic setpoint adjuster
If pneumatic setpoint adjustment is desired, the boost pressure sensors may be used to
supply the signals. For detailed specifications of these sensors refer to chapter 5.5.2.
