The constant running interface must be used on all installations with
constant running hydraulic pumps. The main power supply is led to the
interface and then onto the course computer. The interface unit has
connections for the solenoid valves and the bypass valve, if one is
required. The pump should be wired (as shown) using the specified cable
size and designated circuit breaker.
