The alarm limit setting is A. PID parameters are calculated by measuring overshoot and the time needed to reach peak. The RS interface for configuration from PC is supplied along with the programming software.
Panel mounting, extractable from front. If the Integral Time value is too long Weak yefran actiondeviation between the controlled variable and the setpoint may persist. To mount two manuual more devices side by side, use the cut-out dimensions shown above. It is also possible to set an alarm point related to the current transformer input in order to check eventual load malfunction. The electronic instruments and electromechanical power devices such as relays, contactors, solenoid valves, etc.
The peculiar characteristic of these transformers is the high number of secondary turns. The alarm is reset automatically if the cause of the alarm is eliminated. gefrqn

A in InP for Hb. The direct HB alarm trips if the value of the current transformer input is below the set limit for Hb. Indicates the contents of the various manual sections, the general warnings, notes, and other points to which the reader’s attention should be drawn.
Den Schutz stellen Sie wie folgt ein: It continuously reads system oscillations, immediately seeking the PID parameter values that reduce the current oscillation. As regards electromagnetic compatibility, the strictest generic standards have been adopted, as indicated in the table amnual.
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: For technical specifications and performance details refer to Section 13 “Technical Specifications”. It therefore contains essential information for correct programming and configuration of the controllers.
It does not engage if the oscillations drop below 1. To connect the analogue inputs and analog outputs the following is necessary: The warranty excludes defects caused. The RS interface for configuration from PC is supplied along with the programming software. EMC conformity has been tested with the following connections.

F If possible, to optimize parameters, change the setpoint and check temporary response. RTD type scale configurable within indicated. Don’t show me this message again. PL coldand assesses the effects in timed gefrah.
S Maximum limit of main input scale min It Integral cooling time 0, If the Integral Time value is too long Weak integral actiondeviation between the controlled variable and the setpoint may persist. X Maximum limit heating power 0, For the order code refer gefan Section 14 “Accessories”.
Check that the order code corresponds with the configuration requested for the application the instrument is needed for. The variable for example, temperature must be that assumed at zero power room temperature. This function can be assigned to a digital input d. Electrical Interface All connection terminals power supply, inputs, outputs, options are grouped together on the back of the instrument.
To connect the relay outputs contactors, solenoid valves, motors, fans, etc. Summary of Contents for gefran Page 1 5 m dampened in ethyl alcohol or water to clean the external plastic case.
Fit a 1N diode in parallel with the coil of the inductive loads that operate in Direct Current. Connect with the instrument powered and with inputs and outputs not connected.
Activation at power-on S.
Before proceeding with installation read the following warnings carefully! A configurable personal software protection code password protection can be used to restrict the levels of editing and displaying the configuration parameters.
Any inconsistencies, omissions or evident signs of damage should be reported immediately to your Gefran sales agent. In the event of presumed instrument malfunction, before mahual Gefran Technical Service Assistance, refer to the F. It is activated via the Stu parameter as can be seen on the table, the values to be set depend on whether Gwfran or Soft-start is enabled. If an oscillation persists, increase the proportional band. If the response is too slow, reduce it.
