How to switch the unit ON: To return to normal functioning, press key F for 5 secs. If the response is too slow, reduce it. For more information click here. The warranty excludes defects caused.

HB alarm function also includes control of load current in the OFF interval of the cycle time for the selected output: 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.

EMC conformity has been tested with the following connections. Indicates the contents of the various manual sections, the general warnings, notes, and other points to which the reader’s attention should be drawn. 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 outputs, etc.

If an oscillation persists, increase the proportional band. There is a link for the thermocouple NiCr Ni, 40 K on the front plate.

Activation at power-on S. Make sure the temperature is near room temperature 5. It is essential that the plant has a good earth connection: When finished, the Stun code is automatically cancelled.


Single display controller – Gefran

Indication of load current is displayed by selecting term C. Cut power to the device before accessing internal parts. Setting a limit of A. S Position of decimal point for main input scale 0 Lo.


The power supply lines must be separate from the instrument input and output ones. The alarm limit setting is A. Up to 3 alarm functions assignable to an output. Repairs must be done out only by trained and specialized personnel. The direct HB alarm trips if the value of the current transformer input is below the set limit for Hb.

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”.

PL hotc. S Minimum limit of main input scale min Documentation – Previous versions. By pressing ‘print’ button you will print only current page. To connect the relay outputs contactors, solenoid valves, motors, fans, etc.

The RS interface for configuration from PC is supplied along with the programming software. Don’t have an account? Comments to this Manuals Your Name. It signals variations of load absorption by discriminating the level of current at the transformer input in the range Page of manial Go. Table of Contents Add to my manuals Add. Don’t show me this message again.

Gefdan inconsistencies, omissions or evident signs of damage should be reported immediately to your Gefran sales agent.

ALn is forced to 1 only for mod. It is also possible to set an alarm point related to the current transformer input in order to check eventual load malfunction. Suitable for piloting logic inputs, typical application for interface to solid state switches GTS. In this casethe Stu code is not cancelled.

It continuously reads system oscillations, immediately seeking the PID parameter values that reduce the current oscillation. How to activate self-tuning: L Upper limit for local setpoint and absolute alarms Lo.


Model can have an auxiliary input for a 50mAac current transformer to monitor the load current. Set the setpoint to the required value 2.

If the Integral Time value is too long Weak integral actiondeviation between the controlled variable and the setpoint may persist. The calculated parameters are not saved if the instrument is switched off, if the instrument is switched to manual, or if the configuration code is disabled.

All the programming procedures of the instruments are facilitaded by the grouping of the parameters in function blocks CFG for the control parameters, Inp for the inputs, Out for the outputs, etc. The self-tuning action calculates optimum control parameter values during process startup.
