Jumpers
JP1
Common/Independent Output Control
Pins 1 and 2 jumpered—For the first valve driver board (channels 1 and 2), this causes
both outputs to be controlled from channel 1 program parameters. For the second valve
driver board (channels 3 and 4), this causes both outputs to be controlled from channel
3 program parameters.
Pins 2 and 3 jumpered—Allows outputs to be controlled independently
JP2
Fixed/Variable Peak Voltage duration for Channel 1
Pins 1 and 2 jumpered—Forces a fixed peak voltage duration of 3.5mS for channel 1.
Pins 2 and 3 jumpered—Allow adjustment of peak voltage duration of 1mS to 10mS
for channel 1 using potentiometer P1.
JP3
Fixed/Variable Peak Voltage duration for Channel 2
Pins 1 and 2 jumpered—Forces a fixed-peak voltage duration of 3.5mS for channel 2.
Pins 2 and 3 jumpered—Allows adjustment of peak voltage duration of 1mS to 10mS
for channel 2 using potentiometer P2.
JP4
Fixed/Variable Hold Voltage level
Pins 1 and 2 jumpered—Forces a fixed-hold voltage level of 12 V.
Pins 2 and 3 jumpered—Allows adjustment of hold voltage level of 5 V to 12 V using
potentiometer P3.
Potentiometers
P1 (PTIME1)
Provides adjustment between 1mS and 10mS for channel 1 Peak Voltage duration
when JP2 has a jumper between pins 2 and 3. Clockwise rotation increases duration.
P2 (PTIME2)
Provides adjustment between 1mS and 10mS for channel 2 Peak Voltage duration
when JP3 has a jumper between pins 2 and 3. Clockwise rotation increases duration.
P3 (HOLDV)
Provides adjustment between 5V and 12V for hold voltage level when JP4 has a
jumper between pins 2 and 3. Clockwise rotation increases hold voltage level.
Power Supply Board
