The current limit circuit is adjustable and operates the same as the traction SCR current limit. See
current limit curves for limits and range.
The controlled acceleration circuit is adjustable and operates the same as the traction SCR circuit.
Adjustment range is from .45 to 4.0 seconds.
The variable resistor input will override the fixed motor volt limits set by the three adjustable speed
inputs. It will vary motor volts above the set limits up to full motor volts, as resistance is decreased.
The Battery Discharge Indicator ( BDI ) interrupt will disable the hydraulic controller if the connec-
tion between PB3 and PB6 is opened. If a BDI circuit is not used, a jumper must be placed between
PB3 and PB6 to allow the hydraulic control to operate.
The following are the input/output terminals for the pump control.
