ProSafe Deluxe
Monitor Installation and Trouble Shooting Overview

The ProSafe Monitor System consists of three components. The Zinc Saver, the Main Control Unit and the Display Panel.

The Zinc Saver is spliced in to the green wire coming from the shore cable. There are two ¼” gold plated terminal studs, one on each side of the unit. The stud marked SHORE GROUND is connected to the green wire going off the boat to the dock post. It is the only connection made to this green wire. The 1/4 “ gold stud marked BONDING SYSTEM is connected to the on board Main AC Grounding Buss.

The Main Control Unit has four connections to be made.

1. The Red (+) and Yellow (-) are connected to the DC system on the input side of the DC main breaker. This is used to power the unit.

2. The Brown (line) and Blue (neutral) are connected to the input side of the AC main breaker and the Green (ground) is connected to the AC bonding system buss bar. The AC is used to control the monitor so it operates only when the shore cable is plugged into the dock post and there is power available.

3. The small diameter cable with the 4 pin connector plugs into a mating connector on the Zinc Saver. This cable is the sense cable. Through this cable the ground wire test and the galvanic isolator test are performed.

4. The cable from the display unit plugs into the right side of the Main Control Unit.

VERIFICATION TEST

1. If the monitor system is being used without a bonding system monitor through hull sensor (typical) the Bonding System enable switch must be off. This switch is located on the left end of the main unit (as looked at to read the text). Off is in the down position.

2. Remove the shore cord from the dock post.

3. Switch on the AC sense bypass switch. This switch is located on the left end cap of the main unit. On is up.

4. The ProSafe Monitor will do a self test then test the Galvanic Isolator then test for ground wire – neutral wire continuity test. You can view the self test of the unit by watching the monitor illuminate the display LEDs in a sequence: Ground wire NORMAL, ground wire FAIL, Galvanic Isolator NORMAL, Galvanic Isolator FAIL, pause for a moment and then Galvanic Isolator FAIL. Self test following this sequence assures proper operation of the ProSafe Monitor. After the self test there is a pause of about 6 seconds and then a display of the actual test results. Because we have unplugged the shore cord and turned on the AC sense bypass switch we should experience a ground wire FAIL and a Galvanic Isolator NORMAL.

5. In this step we will simulate a good ground wire. PLEASE, DO NOT STICK ANY WIRES OR TOOLS INTO ANY DOCK POST OUTLET OR INTO ANY TYPE OF AC POWER CONNECTOR. We will be hooking to male shore cord (pins exposed) connectors. Using a short test lead with clips, a large clip by itself or even a bare piece of wire, short the ground prong (G) to the neutral prong (N) on the end of the shore cord. Press the TEST button on the display. After self test and equipment test the monitor will show ground wire NORMAL and a Galvanic Isolator NORMAL.

6. This concludes the verification process. To prepare the ProSafe Monitor for normal operation the bypass switch (left end plate of the Main Control Unit) must be placed into the down, or off, position. The jumper wire you attached to the male plug of the shore cord can be removed and the shore cord plugged into the dock post.

Ground wire failure when plugged into the dock post. Dock wiring troubleshooting.

If upon plugging into the dock post you experience a Ground Wire FAIL condition the dock wiring must be inspected. There are two known conditions that will create a FAIL.

1. The green (ground) wire is not connected to the white (neutral) wire and to earth at the dock side breaker box. This is per the National Electrical Code that the green (ground) be connected to the white (neutral) at this point.

2. There is more then 17 volt AC between the green and the white wires on the boat. This is an abnormal condition and would typically require a system voltage drop of 34 volts overall to attain. This is unlikely as it would bring the panel voltage down to less then 85 volts. It is mentioned because of the possibility that loads are improperly balanced in the dock system.

For the technically inclined.

ALL testing is done upon plug in of the shore cord and every six hours that the shore cord is plugged in, or anytime the TEST button is pressed. Each test lasts 1.5 seconds. During the ground wire test the control unit does a continuity test between neutral and ground. If there is continuity then the display shows a NORMAL if there is not continuity then the display shows a FAIL.

If you have any problems beyond this please do not hesitate to call for technical assistance.
