To Next PageTo Next PageWhy can't I access all parameters and configuration menus on my gefran 2500 Controller?
Access to some menus and parameters is controlled by a password (PAS) and a protection code (PRO), which disables the configuration mode. Refer to Section 4 “Configuration/ Programming” to correctly set the password and protection code.
What to do if I cannot access any configuration menus on my gefran 2500 Controller?
If this occurs during initial installation, it likely means the controller's hardware configuration only allows editing of the setpoint value or the alarm point at level 1. To modify other parameters, adjust jumper S9 on the CPU board.
Why is my Gefran Controller display and LED not turning on?
The issue is likely a controller power supply problem. Verify that power is being supplied to terminals 10-11 and that the power supply matches your order code: 2500 – x – x – x – x – x – 1 for 100..240Vac/dc or 2500 – x – x – x – x – x – 0 for 20..27Vac/dc.
How to fix incomplete or illegible characters on my gefran 2500 Controller display?
This could be due to a fault with one of the display segments. To check, switch the controller off and then on again. During startup, a self-diagnostic test displays '88888' to test all segments. If any segments don't light up, contact your Gefran dealer.
