Gefran 600 controller

Controller display doesn't switch on after being powered?

There is a possibility that the controller is faulty/blown. Kindly download a customer request form, complete and send to Thermon SA (Pty) Ltd. for a quote on repair.

The display of the temperature controller continuously flashes during start-up. What does this mean?

The display should only flash for the first few seconds after start-up. If it continues to flash the power supply is possibly faulty and must be repaired. Kindly download a customer request form, complete and send to Thermon SA (Pty) Ltd. for quote on repair.

How many solid state relays can I drive with a type D logic output from a temperature controller?

You may drive a maximum of 3 GTS gefran solid state relays - this may differ for other SSR brands.

Gefran controllers: LED 1 of the controller flashes on start-up. What does this mean?

This is a possible indication of an instrument that is in Soft-start mode - a function that serves to avoid thermal shock to a heating system. To check if controller is set for soft-start, follow these steps:

Gefran controllers: What is auto-tuning and how can I set it up?

Auto-tuning is an automatic procedure that calculates the best PID control parameters. It is used when the process variable is close to the set point.

SETUP:

Gefran controllers: What is self tuning and how can I set it up?

Self-tuning is an automatic procedure that calculates the best PID control parameters. Self-tuning may only be used when process is launched.

SETUP:

Gefran controller: Can I change the retransmission analogue output to a control output on a 600-x-x-W-x-x?

Yes, the 'W' output card can be used for retransmission or control. For retransmission set An.o = 0 , for control set An.o = 5 or 6.

Gefran controller: How can I retransmit the PV to a PLC with 4-20mA on a 600-x-x-W-x-x?

The standard retransmission setting is 0-10V, but can be changed to 2-10V/ 0-20mA or 4-20mA.

Gefran controller: Can the analog output on a 600-x-x-C-x-x be converted from 0-10V to 4-20mA?

Yes, although 0-10V is the standard output, the analogue signal can be changed to 4-20mA.

Gefran controller: Can the analog output on a 600-x-x-C-x-x be converted from 0-10V to 2-10V?

Yes, although 0-10V is the standard output, the analogue signal can be changed to 2-10V.

Gefran controllers: The top display is showing Hi or Lo. What does this mean?

This is usually an indication that the sensor signal is out of the configured range. Check that the input range is within tolerance:

Gefran controller: The top display is showing Err. What does this mean?

This usually an indication of a) a faulty Pt100 or analogue signal or b) wrong sensor type or c) sensor signal is out of range or d) incorrect/damaged input connection.

Gefran controller: The top display is showing Sbr. What does this mean?

This is usually an indication of a faulty thermocouple temperature sensor (open circuit or faulty cable).
