  • Page 1: Specifications

    Total solder points: 169 + 99 + 67 Difficulty level: beginner 1 advanced TEMPERATURE CONTROLLER K6002 Specifications Accuracy: +/- 0.1°C. Relay outputs: 5A/220VAC change-over contact. Read out from -40°C to +150°C (together with K6001). 24 hour clock (50Hz mains frequency accuracy). Alarm setting from -50°C to +154°C.
  • Page 2 Unlike a normal thermostat this Kit has two outputs, one for a "high" alarm e.g. to switch on a fan or the air conditioning (or to control the temperature of the freezer), and one for a "low" alarm e.g. to switch on the central heating.
  • Page 3 Features & Specifications Features: High and low alarm output with LED indication. Temperature read out in degrees Celsius. Hysteresis adjustable per alarm. Separated opto-coupler sensor input (for K6001). Specifications: Accuracy: +/- 0.1°C. Relay outputs: 5A/220VAC change-over contact. Read out from -40°C to +150°C (together with K6001). 24 hour clock (50Hz mains frequency accuracy).
  • Page 4 Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip.
  • Page 5 REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE CORRECT MOUNTING SEQUENCE ! You will find the colour code for the resistances and the LEDs in the HALG (general manual) and on our website: http://www.velleman.be/common/service.aspx...

  • Page 12 Assembly Final assembly (fig 5.0): Fit the front panel with four 45mm bolts, and push a 10mm distance tube on each bolt. Push the display module on the bolts up to the distance tubes and fix the module by means of four nuts (check if the displays are flush with the front side of the front panel).
  • Page 13 Assembly Then fit the push buttons with their caps (red for select-SW1), fig 6.0. FIG. 6.0 Finally stick the front panel to the front plate. Attention: keep the display window free!
  • Page 14 Adjustment & usage 5.0 ADJUSTMENT AND USAGE Connect a 9VAC supply voltage to the terminals VA and VB. Now, provided everything is all right, the indication FAIL should be displayed (this will be the case after every interruption of the supply voltage), see figure 7.0.
  • Page 15 Adjustment & usage REMARK : The controller won't work (neither the clock) until the temperature sensor has been connected. Following very short power interruptions the controller may get locked up. Therefore leave a pause of about 10 seconds between switching the power off and switching it on again. First switch the power supply of the controller off.
  • Page 16 Adjustment & usage To pass to the next or previous step, push the button shortly. To go through the menu quickly, keep the button pressed. Sequence of the menus (see also fig. 8.0) : 1) TIME indication and setting 2) TEMPERATURE indication 3) LOW ALARM setting 4) LOW ALARM HYSTERESIS setting 5) HIGH ALARM setting...

Desired temperature: 22°C Highest temperature allowed: 26°C Lowest temperature allowed: 19°C Setting the alarms: HIGH ALARM (to switch the fan on) : 26°C HIGH HYSTERESIS (to switch the fan off) : 22°C LOW ALARM (to switch the heating on) : 19°C LOW HYSTERESIS (to switch the heating off) : 22°C...
  • Page 18 Remedies 6.0 REMEDIES IN THE CASE OF MALFUNCTION CAUSED BY THE RELAYS If the relays are used to switch alternating voltage, it may be necessary to suppress them. Figure 9.0 shows how to suppress resistive loads (lamp, resistor, ...). Figure 9.1 shows how to suppress inductive loads (transformer, motor, ...). Figure 9.2 applies in case all the above solutions fail.
  • Page 19 Remedies Pay attention to the diode which is fit ANTI-parallel with the coil, its cathode connected to the plus side, its anode connected to the minus side! This relay MUST be feeded by a separate power supply. The VDR in fig. 9.1 must be suited for the voltage to be switched, e.g. Siemens SIOV S14K275 for use with a 220-240V mains, or S14K150 for a 110-125V mains.
