DIP Switch Functions

The settings of the DIP switches dictate how the control behaves. The system is capable of storing and

instantly retrieving a number of behaviors as presets. The functions of the individual switches are

labeled in the graphic below.

The first three settings, for OFFSET bias, are covered in another section. The PRESET switches allow

selection of 8 different stored control behaviors. In short, the PRESETs are simply storage for different

desired loop control behavior. PRESET storage is discussed at length in another section of this manual.

Slope Inversion

Switch 7, labeled SL/INV inverts the output slope. The default (SW7 OFF) is a 0V (4mA) signal at the

FAR position of the control range. The signal increases as the target gets closer to the sensor. This

behavior is associated with the control of machinery that feeds a process, such as a decoiler. With SW7

ON, the output is inverted such that 0V (4mA) is generated at the near point of the control range and

increases as the target draws away from the sensor. This behavior is requisite for rewinding or other

take-up equipment. The setting of the SW7 dictates how the control will react in a given PRESET

when the set-up procedure is performed.

Master/Slave

SW 8, M/S, is a rarely required but occasionally useful feature. It sets the control as either Master

(default) or Slave. As the latter, the control will only fire after a Master control daisy chained to it

fires. This sets up a multiplexed control pair. It's useful when two loop controls are in very close

proximity and cross-talk becomes an issue.
