Instructions

Compressor Module 101N0800, 12V DC Compressor Module 101N0810, 24V DC

Application Module 101N0820, 12/24V DC

between -25º C and 40 º C is set with the software and the temperature can also be seen by using the interface. When using the “Auto” setting in the software it is not possible to obtain NTC failures, so it is recommended to set the thermostat mode to “NTC” when using a NTC.

Speed selection

Speed can be set through the Secop One Wire/LIN Gateway communication interface (11). With factory

settings, the compressor will run with 2,500 rpm for the ﬁ rst 30 sec. and then step up to 4,000 rpm when the thermostat is switched on. Other ﬁ xed compressor speeds and start speeds in the range between 2,500 and 4,000 rpm can be obtained when changing the speed settings in the software. A start delay in the range from 2-240 sec. (factory setting 4 sec.) after thermostat cut-in can also be chosen.

Fan (Fig. 6, page 2)

An evaporator fan (200W) (5) can be connected between the terminals C and Fe and a condenser fan (100W) (6) between + and Fc . Connect the plus to + and the minus to Fc.

Connecting Fe with Fc

can destroy the unit.

If fans are used without adapting the software settings, the fans will run but no error signal will be sent in case of fan failure. It is also possible to set a start delay on the fans in the range from 0-240 sec. Factory settings for the evaporator fan is 6 sec. and for the condenser fan 0 sec. Fan speed can be adjusted through the interface from 40-100%.

Error handling

If the compressor modules records an operational error, the error can be read out in the software. Error codes are deﬁ ned as shown in Fig. 5.

The application module 101N0820 is a dual voltage device. This means that the same unit can be used in both 12V and 24V power supply systems. Maximum voltage is 17V for a 12V system and 31.5V for a 24V power supply system. The compressor module 101N0810 is a 24V single voltage device. This means that the unit can only be used with 24V DC power supply systems. The compressor module 101N0800 is a 12V single voltage device. This means that the unit can only be used with 12V DC power supply systems.

All modules must be protected

from direct splash water.

Max. ambient temperature is 55°C.

The modules have a built-in thermal protection which is actuated and stops the compressor operation if the electronic unit temperature becomes too high (100°C/212°F on the PCB). The application module can be connected to a PC through the Secop One Wire/LIN Gateway communication interface (11) on the MMI terminal (I/C/+). Communication gateway modules incl. communication cables can be ordered at Secop. The PC interface allows making different settings and reading out several measurements by using the software tool TOOL4COOL® supplied by Secop (must be ordered separately). The application module can also be connected to any modbuscompatible device (12) on the MMI terminal (I/C/+). For detailed information please see the specfic Operating Instructions literature.

Installation (Fig. 6, page 2)

Connect the terminal plug from the compressor module (B) to the compressor(s) (10) and connect the compressor module(s) to the application module (A). The application module will automatically detect whether a twin or a single conﬁ guration is used. For connecting the application module with the compressor module(s) cables supplied by Secop (D) can

be used (Fig. 4 ). Mount the electronic unit on the compressor and ﬁ x it with the two screws (1).

Power supply (Fig. 6, page 2)

All modules must always be connected directly to the battery poles (2). Connect the plus to + and the minus to -, otherwise the modules will not work. The modules are protected against reverse battery connection. For protection during installation, fuses (3) should be mounted in the + cable as close as possible to the modules. Each module must have its own fuse. Recommended fuses and switches (4) are shown in Fig. 3. The wire dimensions in Fig. 2 must be observed. Avoid extra junctions in the power supply system to prevent voltage drop from affecting the battery protection setting. Special supply cables (C) can be ordered as accessories (Fig 4). When using the compressor module 101N0800 (12V) the application module must also be applied with 12V DC. When using compressor module 101N0810 (24V) the application module must also be applied with 24V DC.

Battery protection (Fig. 1)

The compressor stops and starts again according to the chosen voltage limits measured on the + and

- terminals of the modules. The standard settings for the power supply systems are shown in Fig. 1. Other settings are set through the communication interface.

Thermostat (Fig. 6, page 2)

The thermostat is connected between the terminals C and T. Either a NTC (electrical thermostat) (8) or a mechanical thermostat can be connected (7). Another NTC (9) can also be connected between the terminals C and T1 to obtain another temperature. Three different thermostat modes can be chosen in the software – “Auto” (both NTC and mechanical), “NTC” or “Mechanical”. Standard setting is “Auto”. In case of using a NTC the set point in the range

Operational errors

Error code

Error type

Can be read out in the software TOOL4COOL®

Communication failure

(In case of lost communication between the compressor module(s) and the application module, the compressor(s) and fans will be switched off).

Thermostat failure

(If the NTC thermistor is short-circuit, has no connection or is outside the operating range (-60°C - 100°C), the compressor module(s) will switch off and show a NTC failure).

Thermal cut-out of compressor module

(If the refrigeration system has been too hea vi ly loaded, or if the ambient tem pe ra ture is high/ extremely low the compressor module(s) will run too hot/too cold.

Minimum motor speed error

(If the refrigeration system is too heavily loaded, the motor cannot maintain minimum speed at approximately 1,850 rpm).

Motor start error

(The rotor is blocked or the differential pressure in the refrigeration system is too high).

Fan error / Fan missing

(The evaporator fan loads the electronic unit with more than 18A for a 12V system and 9A for a 24V system under start up. The current load exceeds 16.5A for a 12V system or 8.25A for a 24V system under runing conditions).

(The condenser fan loads the electronic unit with more than 9A for a 12V system and 9.5A for a 24V system under start up. The current load exceeds 8.5A for a 12V system or 4.25A for a 24V system under runing conditions).

Battery protection cut-out

(The voltage is outside the cut-out setting, compressor(s) and fans will stop).
