PRIAMOS I
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.
Equally, instead of the knob a clamping fixture can be installed. Ordering specification is
to changed to SW ..-..-k.
6.3 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 set minimum speed according to the 4 mA
value or a programmable substitute value.
6.4 Digital Presetting of Setpoint Values
A 4 bit binary coded digital input for 16 speed levels from nmin to nmax can be directly
connected to the control unit.
6.5 Setpoint Value Adjustment by Pedal
This unit is basically an angular position transducer that translates a foot pedal into a
proportional current or voltage for 0 - 45° rotation. The resulting output can be used for
speed setting. For more information refer broschure E 83 005 - e.
6.6 Pneumatic Setpoint Adjusters
For pneumatic setpoint adjustment are the boost pressure sensors usable. For more
informations of the sensors refer to chapter 5.5.2.
