HT 61 - Multichannel Microprocessor Regulator
This microprocessor-controlled multichannel regulator is available for 5, 10 or 15 temperature control circuits. Measuring values and operating messages of all control zones are displayed simultaneously. You can choose between the display of actual temperatures, set-point values, control deviations or control grades.
Each channel can be individually adjusted to requirements of the respective controlled system.
Up to 4 set points "SP1"..."SP4" can be stored for each channel. In case e.g. "SP4" is selected, all assigned set points are activated with only one keystroke. This allows to adapt the temperature level of all connected control circuits easily and comfortably to different operating modes, e.g. change of material, temperature reduction during breaks in production.
Ramp functions for time-controlled achievement of set points can be programmed. Set points can be monitored for errors, e.g. low temperature, excess temperature, sensor break and sensor short circuit. Two potential-free contacts will trigger in case of error and the error message will be displayed.
Electrically insulated triacs can switch ohmic loads up to 5 A directly, or can switch final controlling elements e.g. solid state relays. HT 61 is equipped with a diagnostic program which can be started after initial installation or in case of errors. It performs plausibility checks and detects e.g. cable mistakes, polarity reversals, short circuits and cable breaks.
Each HT 61 channel can also be operated as a power controller without temperature measuring, the control grade is displayed in percent.
