  • Page 4: Settings

    4. Settings The cooling unit is intended to be used as a complementary accessory to larger industrial equipment. The unit is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to protect heat sensitive components. It is not intended for household use. The unit has two completely separate air circuits which ensure that the clean cabinet air does not come into contact with the ambient air which may well be dirty or polluted.

  • Page 5: Functional Principle

    5. Functional principle The cooling unit for enclosures works on the basis of a refrigeration circuit consisting of four main components: compressor, evaporator, condenser and expansion device. The circuit is hermetically sealed and R134a refrigerant circulates inside it (R134a is chlorine free and has an Ozone Destruction Potential [ODP] of 0 and a Global Warming Potential [GWP] of 1430).

    14. Controller The display shows the temperature in the range of -22°F to 230°F. The temperature is displayed with a resolution of 32.18°F between 14.8°F and 210°F, and 32°F between -22°F and 14°F, and between 212°F and 230°F. On start-up, the screen shows the unit’s internal temperature, and this is considered the Home Menu of the controller.

  • Page 17 Gateway operation only rather than for Client use and a Modbus Controller will not be able to communicate with the units anymore. The Seifert Gateway acts as a Slave in the Master/Slave network and will still be able to communicate with the Master.
  • Page 18 When a network is in MSR mode, the flashing of the 4th digit dot (right most digit), indicates the status of the unit in the MSR status. Below is a table describing the flashing based on the unit status. Master settings MS2: Master Modes None: All units are Independent of each other.
  • Page 19 ii) Redundancy Mode Redundancy settings Display Description Redundancy Modes: None, Mode A, Mode B Start-up Mode Changeover Timeout in Minutes RS1: Redundancy Modes: None: No redundancy, all units operate normally Mode A: In this mode, there will be 2 sets of units, and they will toggle between each other after a pre-defined time. The start-up units are settable.
  • Page 20 The redundancy time increases only if there is at least one active (non-redundant) unit cooling from the active units group. The changeover between units happens only if no active unit is cooling. Modbus Communication Detailed instructions on Modbus communication can be found in the link below. https://seifertsystems.com/site/assets/files/6903/rdtg2001-0_2_-_generic_modbus_table.pdf Futher notes: From Modbus side, any setting can be with 32.18°F precision.

  • Page 22: Taking Into Operation

    16. Taking into operation Attention! The unit can be damaged by lack of lubricant. To ensure that the compressor is adequately lubricated the oil, which has been displaced during transport, must be allowed to flow back into it. The unit must therefore be allowed to stand for at least 30 min.

  • Page 23: Maintenance & Cleaning

    18. Maintenance & Cleaning Always switch power supply off before starting any maintenance on the unit. Wait for 5 minutes for electrical components to discharge. The cooling unit is generally maintenance free and can be operated without filters in most environments. If the ambient air is extremely dusty, we recommend installing filter mats (see accessories).

  • Page 24: Transport & Storage

    19. Transport & Storage Malfunction due to transport damage On delivery the carton box containing the unit must be examined for signs of transport damage. Any transport damage to the carton box could indicate that the unit itself has been damaged in transit which in the worst case could mean that the unit will not function.
