General Overview

Level Sensor 1 : 0-190Ω resistive sensor Level Sensor 2 : 240-33Ω resistive sensor Level Sensor 8 : Detection of leakage current. The connection to the hull is done by any conductor (a priori, green/yellow because the hull must be connected to the ground) of 1.5mm² section. Note : All Level Sensor inputs (numbered 1 to 8) are strictly identical and can be individually configured in each mode. The only exception: leakage current detection is only accessible on Level Sensor #8 if it is not used by another mode. Aux Input 1 : Dry contact, push button type, door contact, presence detector,...

The [reinforcement] output must be connected as symmetrically as possible with the [master] output (cross connection on - and +, short shunt with high section) From previous module ShipPower8DC Circuit 1 : Bipolar circuit. Maximum allowable current of 25A Circuit 3 : Single pole circuit. Maximum allowable current of 25A Batteries pack #1 Circuit 7 : Bipolar circuit [maitre] Circuit 8 : Bipolar circuit [reinforcement] of circuit 7. Only circuit 7 appears on ShipHeart. Its maximum current rating is 40A The battery pack voltage is either 12V or 24V. Powering ShipPower8DC from independent...

The braid of each ShipBS must be connected directly to the negative terminal of the monitored battery. All connections to the "0V" of said battery must be made to the fixed terminal of the ShipBS. ➔ NO connections other than the ShipBS braid should be made to the negative terminal of the battery. Using ShipBS on 12V and 24V battery packs is not a problem as long as their grounds (0V) are connected together. According to ISO EN 13297-2020 in chapter 5.1 "Schemes with multiple battery banks must have a common negative terminal." From previous module Generator batteries Engine batteries...

Passage in the torus of the corresponding output Galvanic isolator Shore outlet Wiring in 6mm² conductors except connections to ShipPower4AC in 1.5mm². In this arrangement, the shore power has priority over the generator. If the shore power is activated, the generator input is disconnected. CT01 Generator As stated in Section 6.6 of ISO EN 13297-2020 "Individual circuits shall not be capable of being supplied by more than one power source at a time. Each power supply, shore power, generator or converter is a separate source of electrical energy. The transfer of a circuit from one power...

Passage in the torus of the corresponding output Circuit 1 : 32A via external contactor. Main wiring in 6mm². Contactor wiring in 1.5mm². Circuit 2 : 20A via external contactor. Main wiring in 2.5mm². Contactor wiring in 1.5mm². Circuit 3 : 10A Wiring in 1.5mm² Circuit 4 : 2A Wiring in 1.5mm² The input of each circuit of a ShipPower4AC is equipped with a female movable plug (thus protected against accidental contact when not plugged in). Max current per circuit : 10A without external contactor 32A via external contactor The output of each circuit is equipped with a mobile male plug. Earth...

1. First start-up of 2-3 minutes. Current exceeds 10A - which does not recur on subsequent cycles - showing that starting up after a long period of inactivity is forcing the compressor. 2. The fast shutdown is probably due to one of its protections. 3. Second start with lower current. The operation lasts much longer; probably until the desired temperature is reached. 4. The following peaks are maintenance start-ups, relatively regular. 5. The battery has a satisfactory voltage before the compressor starts. 6. The voltage drop is very reasonable despite the high power consumption of the...
