7 Setpoint adjusters
Digital Governor Basic System PANDAROS II 21
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
With the corresponding configuration, a digital setpoint selection (e.g. digital
synchronization performed manually or via PLC) can be implemented directly via two
switch inputs (higher/lower speed).
7.5 Setpoint value adjustment by pedal
The electronical foot pedal EFP 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 6.4.2.
