It will be similar to that in the figure: PID parameters are calculated by measuring overshoot and the Process time needed to reach peak. Make sure the temperature is near room temperature 5. Model can have an auxiliary input for a 50mAac current transformer to monitor the load current.

The alarm limit setting is A. Fit a 1N diode in parallel with the coil of the inductive loads that operate in Direct Current. RTD manuaal scale configurable within indicated.


Cut power to the device before accessing internal parts. Before proceeding with installation read the geran warnings carefully! The warranty excludes defects caused Power supply cable 1 mm Relay output cables 1 mm grfran m by any use not conforming to these instructions. L Upper limit for local setpoint and absolute alarms Lo. How to switch the unit ON: Suitable for piloting logic inputs, typical application for interface to solid state switches GTS.

Current transformer input variable AL. This provides a very low secondary current, suitable for an electronic measurement circuit. It is essential that the plant has a good earth connection: The RS interface for configuration from PC is supplied along with the programming software.


It continuously reads system oscillations, immediately seeking the PID parameter values that reduce the current oscillation. Fix the device with the bracket provided before making any electrical connections. 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.

It is advisable to make sure that alarm signals are also triggered during normal operation. Laterally, heaters can be steered through the automatic controller. The warranty excludes defects caused.

Don’t have an account? S Position of decimal point for main input scale 0 Lo. D The PID parameters are calculated s follows: Set the setpoint to the required value 2.

The power supply lines must be separate from the instrument input and output ones. 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.

Panel mounting, extractable from front. The variable for example, temperature must be that assumed at zero power room temperature. To print the manual completely, please, download it. Deviation indicator On if deviation is between 0. 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.

Default Custom 0 S. Setting a limit of A.

The self-tuning action calculates optimum control parameter values during process startup. The alarm is reset automatically if the cause of the alarm is eliminated. HB alarm function also includes control of load current in the OFF interval of the cycle time for the selected output: The board is automatically recognized by the instrument, which enables display and setting of the parameters involved.


The electronic instruments and electromechanical power devices such as relays, contactors, solenoid valves, etc. These keys are used for any operation that requires a numerical parameter to be raised or lowered.

If the Integral Time value is too long Weak integral actiondeviation between the controlled variable and the setpoint may persist. Table of Contents Add to my manuals Add.

If the response is too slow, reduce it. S Minimum limit of main input scale min As regards electromagnetic compatibility, the strictest generic standards have been adopted, as indicated in the table below. For technical specifications and performance details refer to Section 13 “Technical Specifications”. There is a link for the thermocouple NiCr Ni, type K on the front plate.

To semplify the configuration manuall 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. Activation from keyboard 1. Turn on the instrument manua, B. Indicates manul contents of the various manual sections, the general warnings, notes, and other points to which the reader’s attention should be drawn.
