Theory of Operation

The engineers at Professional Mariner have designed the ProSafe One Monitor in
such a way that it connects to your electrical/bonding system for only a very short
amount of time over the period of a day, less then 20 seconds in a 24 hour period.
We have done this because we feel that any type of voltage, AC or DC, left on the
bonding system for extended periods of time can be detrimental to the integrity of
the bonding system’s fittings and struts in contact with seawater.

Each time the vessel is connected to AC shore power, or the ProSafe One Monitor
is activated by the push to test button, or every 3 hours after that, the ProSafe One
Monitor does a series of tests. First it performs a reverse polarity test. Then it performs
the tests required in ABYC A-28: a test of the ground wire continuity and then the
integrity of the Galvanic Isolator. The actual test results are displayed on the remotely
mounted display panel.

“FAIL” indication of the ground wire

WARNING!

DO NOT PERFORM THIS TEST IF THE PROSAFE ONE IS INDICATING A
"REVERSE POLARITY FAIL". INSTALLING THE JUMPER WIRE IN STEP 2
BELOW DURING A REVERSE POLARITY CONDITION WILL PUT HIGH VOLTAGE
ONTO THE BONDING SYSTEM. THIS IS A LIFE THREATENING CONDITION.

1. Be sure the shore power cable is disconnected at the dock post.

2. Using a length of jumper wire (18 ga. or larger) connect one end to the neutral
wire (connection location of the ProSafe One blue wire) and the other end to
the shore ground wire ("AC Shore Ground" stud on the Galvanic Isolator). With
the boat's AC main breaker in the "off" position, reconnect the AC shore cord
to the dock post and turn on the dock post breaker. After the five second test,
the display should show a "NORMAL" condition on the ground wire indicator.
With the display showing a "NORMAL", the problem could be a defective shore
cable, a shore cable connector or faulty ground/neutral connection dockside.

In the event you are new at this dock and the ProSafe One has not given you
a "FAIL" indication previously, it has been found that a bad ground/neutral
connection at the dock is a likely occurrence.

If the ProSafe One shows a "FAIL" during this test of the system, the ProSafe
One has failed and needs replacement.

UPON COMPLETION it is imperative that you disconnect the shore cord from
the dock post and then remove the jumper wire. Not removing this jumper is
in violation of ABYC standards.

CAUTION - Because of the presence of deadly high voltages troubleshooting should
be done by a qualified service person only.
