LED with various flashing modes depending on the type of security that has been set. See chapter 3.8 - Alarms 3.9 - OPERATIONAL INSPECTION The following indications are valid if the system has been installed according to the diagrams provided.Before the inspection, set the thermostat to –10°C for refrigerator for boats plates or –20°C for freezer plates, or set the timer if appropriate. 3.9.1 – ELECTRICAL INSPECTION Battery not charging This depends on the electric box being used. CHARTER electric box DIGITAL electric box This depends on whether you have CA connection or if terminals 0 and 1 have been bridged.1) CA contact inserted in boat terminal 1 In these conditions the pump, ventilators and compressors must NOT function. 2) Bridge between terminals 0 and 1. In this case the unit must operate correctly, therefore seawater pump, ventilators and compressors should start as usual. Be aware of the risks described in the previous chapter regarding this type of configuration. Battery undercharged The unit’s behaviour depends on the value set for the V cut-out:1) V cut-out > V battery Thus seawater pump, ventilators and compressors must not operate. 2) V cut-out > V battery the system must operate correctly until the battery begins to run down and V battery < V cut-out. At this point the electronics will cut off the power supply and the pump, ventilators and compressors will stop. CHARTER electric box In this case, whether you have a CA contact in terminal 1, or terminals 0 and 1 bridged, seawater pump,ventilators and compressors should function. DIGITAL electric box If the ‘V cut in’ has been set correctly by following the instructions in paragraph 3.6, the system should operatecorrectly, and therefore seawater pump, ventilators and compressors should start.With an undercharged battery, with both the charter and digital boxes, the refrigerating unit will operate until theThermostat or timer so allow. 3.9.2 – CHECKING SMOOTH FUNCTIONING When you have made sure that the cooler has been started in the correct manner and according to the correcttiming, the next thing you need to do is check that everything is running smoothly during operation. To do this, follow these steps: 1) make sure the cooling water is flowing correctly. The required quantity is 4 l/min. 2) After a few minutes the holding plate will begin to cool. 3) Place your ear next to the thermostatic valve installed on the holding plate. You should hear a distincthissing. This is the coolant running through.4) The dehydrator filter must never become hot.

5)

Check the absorption of the compressors with an amperemeter. With 12V power supply, the unit shouldabsorb 16 A +- 2 A. With 24V power supply, it should absorb 8 A +- 1.5 A.

6)

After approximately 60 minutes (small and medium plate) the thermostat (if installed) should stop thecompressor. The large plate requires 90 minutes and the maxi 120 minutes to reach total holding. The freezer plates (marked –22) require 30% more time to reach total accumulation.

7)

If you tap the unfrozen holding plate, you will hear a metallic sound. When frozen, the sound is muffled. 9
