Application Enclosure cooling units are designed and built to dissipate heat from enclosures, by cooling the air inside the enclosure and protecting temperature sensitive components. Enclosure cooling units are particularly suitable for the temperature range of + 40 °C to + 55 °C. 2. Technical Data (see table 2.1) 3. <strong>Assembly</strong> The cooling unit can be mounted internally or externally. Make cutouts and drill holes at the mounting position (see fig. 3.1). Cut the seal provided to length and attach it to the back of the unit (fig. 3.2). Screw 10 setscrews M6 x 30 into the blind nuts at the back of the unit. Fix the unit in the mounting position, using 10 washers A 6.4 and 10 nuts M6. Fix the condensate discharge tube. Prior to mounting, ensure that: the site for the enclosure, and hence the arrangement of the cooling unit, is selected so as to ensure good ventilation; the location is free from excessive dirt and moisture; the round cut-out for air extraction is located in the upper area of the enclosure; the mains connection ratings, as stated on the name plate, are available; the ambient temperature is no higher than +55°C; the packaging shows no signs of damage; the enclosure is sealed on all sides. Condensation will occur if the enclosure is leaky; the separation of the units from one another and from the wall should not be less than 200 mm; air inlet and outlet are not obstructed on the inside of the enclosure; units are only fitted vertically in the specified position. Max. deviation from true vertical: 2°; condensate discharge must be made up by means of the material provided in the dispatch bag. The discharge tube must be free from kinks and must be arranged sloping away from the unit; electrical connection and repair are carried out only by authorized specialist personnel. Use only original replacement parts! To avoid an increase in condensation, a door operated switch (e. g. PS 4127.000) should be used which will switch the cooling unit off when the enclosure door is opened (see 5.2.3.3). 4. Electrical Connection The connected voltage and frequency must correspond to the values stated on the name plate. The cooling unit must be connected to the mains via an isolating device, which ensures at least 3 mm contact opening when switched off. The unit must not have any additional temperature control connected before it. Line protection should be provided by means of the pre-fuse specified on the name plate. Observe the relevant regulations during installation! Version .....100 Connection should be made to the cable attached to the unit (see Detailed Wiring Diagram, page 35). Version .....500 Connect the mains connection to the plug-in terminal strip X 10, see page 35. Door limit switch, see 5.2.3.3 Collective fault signal connection, see 5.2.3.1 Note the designations on the terminal strip (see wiring diagram). The unit must be disconnected prior to checking the protective earth conductor, high voltage and the insulation in the enclosure. 5. Commencing Operation and Control Behaviour Following the completion of mounting and a waiting period of approximately 30 minutes (to allow oil to collect in the compressor in order to ensure lubrication and cooling) electrical connection can be made. 5.1 Control by Thermostat Version .....100 The cooling unit operates automatically, i.e. following the electrical connection, the evaporator fan will run continuously to circulate the air inside the enclosure. This provides a uniform temperature distribution in the enclosure. The built-in temperature controller (setting the desired internal temperature) effects automatically controlled switch-off of the cooling unit by the value of the fixed switching difference setting of 5 K. This is set at the factory to + 35°C. 5.1.1 Temperature Setting at the Controller Fig. 5.1 Thermostat 20 30 1. Remove the setting knob after slackening the screw. 2. Remove locking plate. 3. Replace the setting knob and set the desired temperature. Setting range + 20°C to + 55°C. 4. Replace the locking plate and fix the setting knob by tightening the screw. 5. To avoid cyclic operation of the compressor, it is imperative that the set switching difference of 5 K is not changed and does not deviate to a lower value. 40 50 60 25 35 45 55 °C °C °C 10 8 6 4 3 Diff. 5.2 Control by Microcontroller Version .....500 Fig. 5.2 Microcontroller H1 H3 H2 °C TEST ENTER °F H4 H5 After electrical connection the internal fan turns on and circulates the enclosure air. This helps assure even temperature distribution within the enclosure. The condensor fan and compressor are controlled by the microcontroller. The minimum run time is 90 seconds. The switching difference is 5 – 10 K and is set at the factory. In order to maximize energy efficiency the thermostat should be set to the highest enclosure temperature as allowed by the electronics. 5.2.1 Operation of the Microcontroller The display terminal H1 consists of a 3 position 7-segment display which indicates the enclosure internal temperature in °C or °F (changeable, see section 5.2.2) as well as any fault codes. The actual enclosure internal temperature is constantly displayed. If a fault occurs then the fault number is indicated in the left position. When programming the microcontroller the program level and parameter value is indicated on the display. When the “TEST” button is pushed the compressor and the fans will run for 5 minutes regardless of the internal temperature or door limit switch. This allows for a system test after an extended shutdown period (e.g. after the winter). 5.2.2 Programming (see diagram 5.1, page 39) In the EEPROM of the microcontroller various parameters are stored which can be changed through using the “ENTER” and “ ” buttons, 9 different parameters are changeable as outlined in table 5.1. To access the programming mode push both the “ENTER” and “ ” buttons simultaneously for 10 seconds. The left digit will then indicate the program level and the LED for the “ENTER” and “ ” buttons will blink. By pushing the “ ” button the program level can ➡ ➡ H1 = Display Terminal H2 = LED °C H3 = LED °F H4 = LED ENTER H5 = LED ➡ be advanced to the next level. In order to access levels 5 through 9 a security code must be entered. If no buttons are pushed for 60 seconds the display will return to the standard mode which displays the enclosure temperature. Programming of the parameters is made easy with diagram 5.1 on page 39. A description of the parameters to be programmed can be found in table 5.1. All parameters are stored in the EEPROM and are retained when power is shut off to the air conditioner. ➡ ➡
