block on the Actuator circuit board labeled ALARM. It is located
next to the DC Power terminal.
The alarm circuit in the Actuator is designed to operate a relay
in an alarm system supplied by others. The resistance through
the Actuator to battery negative is approximately 21 ohms.
Maximum current draw must not exceed 200 milliamperes.

The purpose is to prevent clutch engagement at high engine
RPM. The Clutch Oil Pressure Interlock will block a speed signal
to the engine until the hydraulic clutch pressure has reached a
value recommended by the transmission manufacturer that
assures clutch lock-up.
To take advantage of the Clutch Oil Pressure Interlock, the 585
Actuator must be set up to use the 'HI' idle 'LO' idle option
described in Section 7.1. This means that the fifth station is not
available.
• Move JMPR 1 shunt to pins 1 and 2.
• Move JMPR 2 shunt to both pins.
The requirement is a N.C. (Normally Closed) pressure switch
with a trip point adjustable to match the transmission
manufacturers recommended setting. The pressure switch is
supplied by others. The pressure switch is operated by the
hydraulic clutch oil pressure of both the 'AHEAD' or 'ASTERN'
clutch.
When Terminals 3 and 4 of Station 5 (see Figure 9) are
connected, the engine speed signal is held at "idle". Therefore,
connect Station 5 terminals 3 and 4 to the N.C. pressure switch.
The engine speed signal will be held at "idle" until the clutch oil
pressure opens the pressure switch contacts.
