Mounting

Always switch off the power supply before starting any work on the unit.

Installation
Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed. Before drilling the enclosure, ensure the fixing elements and couplings will not interfere with the equipment inside the enclosure itself. When all mounting preparations are complete the actual mounting operation can commence. Only use the enclosed material to mount the unit on the cabinet.
Proceed as follows to mount the unit on the cabinet:

• Set the unit up on the cabinet.
• Ensure that the electrical connection is above the internal fan.
• Unit without duct: screw the M6 locknuts & washers into the M6 set screws in the unit.
• Unit with duct: screw the M6 screws & washers into the M6 threaded rivets in the unit. The resistance of the earth connection between the cabinet and cooling unit must be <0.1Ω.

Condensate management

Depending on the mounting situation the condensation management may need to be considered and possibly adjusted.

Mounting Principle

In order to maintain the TYPE 4X rating, the tightening torque for this unit should be 4.5 Nm and needs to follow the below sequence.

Electrical Connection

High electric voltage present. Installation, maintenance, cleaning and any other work must be carried out by qualified personnel only. The personnel must ensure that for the duration of this work the unit and the cabinet are disconnected from the electrical supply and protected against unauthorised/accidental reconnection.
Instruction: Check that the available voltage, frequency, and fuse rating are the same as those stated on the unit data label.
Connection to the main electricity supply
The main connection is made via a cable. To connect the unit to the mains supply proceed as follows:

• Disconnect the control cabinet from the mains.
• ​See the connection details on the circuit diagram.
• Note the connections on the three-pole terminal blocks from the following diagram.

Terminal 230 V ~ 50/60 Hz

• L Live
• PE Protective Earth
• N Neutral

Ensure that the correct polarity is maintained.

• The fans should have a clockwise rotation.
• Connect the unit to the mains.
• Take the control cabinet back into operation in the prescribed manner.

Power consumption and start-up current are stated on the data label and under technical data.

Controller

The display shows the temperature in the range of -50°C to +150°C (-58°F to +302°F). The temperature is displayed with a resolution of tenths between -19.9°C and +99.9°C (-3.8°F to +211.8°F). During programming, it shows the codes and values of the parameters. The display also shows icons according to occurring events.

Programming
The operating parameters can be modified using the front keypad. Access differs depending on the type of parameter. Access to configuration parameters is protected by a password that prevents unwanted modifications or access by unauthorized persons.
Setting cooling set point, St1:

1. Press “SET” and the display should show St1 and then the pre-set value of St1. (default: +35°C / +95°F)
2. Reach the desired value by using ▲ or ▼.
3. Press “SET” again to save the new value of St1.

​Setting temperature units (°C / °F), low-temperature alarm, and high- temperature alarm:

1. Press the “PRG” button for 5 seconds to reach the modifiable parameter list.
2. Use ▲ or ▼ to reach the desired parameter:

• C18 for temperature unit of measure
• °C = 0
• °F = 1
• P25 for low-temperature alarm threshold (default -10°C / +14°F)
• P26 for high-temperature alarm threshold (default +55°C / +131°F)

1. Press “SET” on the desired parameter to display the current value.
2. Use ▲ or ▼ to reach the desired value.
3. Pressing “SET” temporarily saves the new value and returns to the parameters list.
4. Repeat steps 2-5 to set other parameters.
5. Press “PRG” for 5 seconds to permanently save the new values.

Set Point Parameter Default Range

• Cooling St1 35°C / 95°F 20°C – 50°C / 68°F -122°F
• Low Temperature Alarm P25 -10°C / 14°F -50°C – P26 / -58°F – P26
• High Temperature Alarm P26 55°C / 131°F P25 – 150°C / P25 – 302°F

Test function
Different test functions can be used depending on the combination of keys pressed. Such tests run for the duration of 4 minutes.

• “SET+▲” tests cooling relays
• “SET+▼” tests alarm relays

Important Notes

• Whilst programming, if no button is pressed for 10 seconds, the display starts flashing, and after 1 minute returns to the main display without saving changes.
• To increase scrolling speed, press and hold the ▲ or ▼ button for at least 5 seconds.
• When pressing “PRG” for 3 seconds, the firmware revision code is displayed for 2 seconds.
• When cleaning the controller panel, do not use ethanol, hydrocarbons, ammonia or their by-products. Use neutral detergents and water.

The hysteresis is 5K, the minimum ON-time is 0s, the minimum OFF-time is 0s.

Wiring Diagram

Taking into Operation

• The power supply rating on the rating plate must comply with the mains supply
• Always disconnect the power supply before opening the unit.

Heat load to be dissipated from the enclosure should not exceed the specific cooling output of the unit at any condition. While selecting a cooling unit always cater for a safety margin of at least 15% extra cooling output. The Peltier – elements should be controlled by a suitable thermostat. Models TG 6XXX with 100 – 230 V supply have already a controller integrated.
Trouble Shooting
In case of a fault please contact your nearest servicing office. A list of service partners can be found on our website www.seifertsystems.com
Maintenance & Cleaning

• Always switch off power supply before starting any work on the unit. Only qualified personal may conduct any maintenance work on the cooling unit.
• All Peltier units are virtually maintenance-free and no filters which need to be cleaned or replaced. Check the ambient heat sinks from time to time. In case they are dirty proceed as following:
• Disconnect the enclosure from the mains.
• Clean the heat sink profile as required by blowing it out with compressed air.
• In cases of extreme pollution wet cleaning is required.
• The unit must be removed from the control cabinet for wet cleaning

Should a wet cleaning be necessary proceed as follows:

• Disconnect the whole plant from the mains.
• Remove the unit from the cabinet.
• Ensure that the seals are not damaged.
• Wash the heat sink with an environmentally safe cleaning fluid.
• Danger to the environment through unauthorized disposal.

Disposal
Dispose of cooling unit and used parts with due regard for the environment and in accordance
with environmental laws and regulations.

Maintenance

Note: Only use original replacement parts when repairing the unit. This ensures that the unit functions perfectly and remains safe.

Fan replacement: The average working life of the fan is ca. 40,000 hours under normal conditions. Should a fan replacement be necessary proceed as follows:

• Disconnect the unit from the mains.
• Remove the unit cover.
• Remove the screws from the relevant fan.
• Mount a new fan.

Danger: to the unit through incorrect work.
Make sure that the cabinet fan or the ambient fan are not misplaced in the unit as they are different. Ensure that the correct polarity is maintained. The fans must rotate clockwise!

• Replace the 4 fan fixing screws.
• Close the unit and take it back into operation.

Transport & Storage

During transport and storage, the cooling unit must be kept in the position marked on the box and at a temperature between -40˚C and 70˚C and a relative humidity of max. 95% (at 25°C). In case of damaged packaging after transport or in-house handling, we recommend controlling the unit for any internal damages.
