How to switch the unit ON: RTD type scale configurable within manuwl. The RS interface for configuration from PC is supplied along with the programming software. Table of Contents Add to my manuals Add. Activation at power-on S.
It can be one of two types: Download file – link to post. Setting a limit of A. Use of these solvents can reduce the mechanical reliability of the device. Page of 13 Go. These keys are used for any operation that requires a numerical parameter to be raised or lowered.
S Digital filter on main input 0, Indicates a particularly delicate situation that could affect the safety and correct working operation of the controller, or a rule that must be strictly observed to avoid dangerous situations Indicates a suggestion based on the experience of the GEFRAN Technical Staff, which could prove especially useful under given circumstances Indicates a reference to Detailed Technical Documents available on the GEFRAN web site www.
The main input for the process variable is universal and provides the possibility to connect many manula of input sensor: It does not engage if the oscillations drop below 1. L Lower limit for local setpoint and absolute alarms Lo. Model can have an auxiliary input for a 50mAac current transformer to monitor the load current.
Single display controller – Gefran
To mount two or more devices side by side, use the cut-out dimensions shown above. HB alarm function also includes control of load current in the OFF gefrsn of the cycle time for the selected output: Panel mounting, extractable from front. Got it, continue to print. To connect the analogue inputs and analog outputs the following is necessary: All the programming procedures of the instruments are facilitated by the grouping of the parameters in function blocks CFG for the control parameters, Inp for the inputs, Out for the manuual, etc.
Bring the temperature near room temperature 3. Cut power to the device before accessing internal parts.
How to activate self-tuning: Turn off the instrument t. S Maximum limit of main input scale min S 0 1 2 3 Format xxxx xxx. It signals variations of load absorption by discriminating the level of current at the transformer input in the range Check that the order code corresponds with the configuration requested for the application the instrument is needed for. It is activated via the Stu parameter as can be seen on the table, the values to be set depend on whether Self-tuning or Soft-start is enabled.
RTD 3 wires 16 17 Max. To print the manual completely, please, download it. If the Integral Time value is too long Weak integral actiondeviation between the controlled variable and the setpoint may persist. When the electronic instrument power supply is strongly disturbed by the commutation of transistor or power units or motors, an isolation transformer should be used for the controllers only, earthing the screen.
To semplify the configuration even further, a programming kit is available for PC, which includes a menu driven configuration program for Windows and the necessary cable to connect the instrument see technical data cod.
SP Cooling setpoint relative to heating set Use wires of adequate thickness min. Electrical power supply essential to connect it up to auxiliary alarm equipment. The main input for the process variable is universal and provides the possibility to connect many types of input sensor: It therefore contains essential information for correct programming and configuration of the controllers.

The alarm limit setting is A. Set the setpoint to the required value 4. Connect with the instrument powered and with inputs and outputs not connected. Do not clean the case with hydrocarbon-based solvents Petrol, Trichlorethylene, etc. Current transformer input variable AL. Comments to this Manuals Your Name. In case of double action heating or coolingparameters for the opposite action are calculated by maintaining the initial ratio between parameters ex.: For technical specifications and performance details refer to Section 13 “Technical Specifications”.
A in InP for Hb. As regards electromagnetic gevran, the strictest generic standards have been adopted, as indicated in the table below. These details must always be kept close at hand and referred to the personnel involved in the event of help from Gefran Customer Service Assistance. To return to normal functioning, press key F for 5 secs. This provides a very low secondary current, suitable for an manuap measurement circuit.
