DART Controls 13DVA Series Instruction Manual page 30

Setting the Min, Max, Balance and Linearity Trimpots.
1. Preset the multi-turn Linearity trimpot and the Balance trimpot on the –7 option board full CW, set the Min trimpot full CCW
and set the Max trimpot at about 50% rotation.
2. Input a 4 ma. current signal to the control and turn the Min trimpot CW to your desired minimum output voltage or to deadband
(the point just before you begin to get an output).
3. Input a 20 ma. current signal to the control and set the Max trimpot to the desired maximum speed setting.
4. Switch the control to the Manual mode setting and adjust the Balance trimpot CCW as needed to attain your required manual
mode maximum output speed. (Adjustable form 50 to 100% of maximum Auto mode setting)
5. Switch the control back to Auto mode. With 20 ma. still going to the control, turn the Linearity trimpot CCW until your
output speed starts to decrease. Then slowly turn it back CW until you just reach your maximum speed setting.

Manual Forward-Off-Reverse Switch
Permits reversing of motor. This is accomplished using a 4PDT blocked center switch. When switched between the forward/reverse
positions, a delay is encountered due to the blocked center position, which protects the control from any voltage that may be at
the ARM terminals. The center position is OFF/NEUTRAL.
THE MOTOR MUST COME TO A COMPLETE STOP BEFORE CHANGING DIRECTIONS. IF THE MOTOR DOES NOT COME
TO A COMPLETE STOP, SERIOUS DAMAGE TO THE CONTROL MAY RESULT. BYPASS OF THE SWITCH CENTER BLOCK
MAY RESULT IN DAMAGE TO THE CONTROL.
