Display is blank and LEDs are neither blinking nor glowing
Problem:
There is nothing displayed by controller, display backlight is off and LEDs are not flashing or
glowing.
Solution:
a) There is no power supply voltage. Check the power supply voltage.
b) Boot jumper is closed, switch controller off, open the jumper and switch controller on.
Display is blank, but backlight works
Problem:
There is nothing displayed by controller, but display backlight is on.
Solution:
a) Previous controller programming failed, follow instructions in the
Unsuccessful controller
programming
section.
b) IG-NT, IG-Display: Display contrast is set to an extremely low value. Hold Enter and push the
arrow up
↑ button then to increase contrast.
Display is showing “Unsupported code page”
Problem:
The following message is shown on the display:
Unsupported code page
Solution:
The language used in the controller is not supported in the display (unsupported languages
with graphical characters). In this case, change the language of the controller and contact
ComAp to get more information about supported graphical languages (by default Chinese and
Korean).
INIT is displayed and controller mode cannot be changed
Problem:
The unit shows "INIT" and does not work, controller mode can not be changed. This situation
occurs after controller reset. Reason of the problem are either incorrectly set setpoints or flat
RTC battery.
Solution:
a) A new firmware containing new setpoints was uploaded into a controller. Use InteliMonitor
online connected to the controller to check all setpoints and fix setting of those which are set in
a wrong way. You have to change at least one setpoint setting. If all setpoints are correct,
change one of them and put it back to the original value to recalculate the checksum. It may
be necessary to switch controller off and on after changing setpoints setting. You can tick
Reset from Init state function in Options in GenConfig to avoid repeating of this problem (Init
state reset is done automatically by GenConfig if this function is active).
b) The RTC backup battery is flat. Send a controller to your distributor for battery exchange if the
RTCbatteryFlat message is displayed

External display problems
No reaction to pushing command buttons or setting adjustments
Problem:
It is not possible to adjust any setpoint setting and issue any command using IG-NT panel,
IG/IS-Display module or InteliVision (IV).
Solution:
Access lock input is active for that particular terminal, therefore this terminal can be used only
for monitoring. You can check this by looking on the first measurement screen (press Esc to
enter menu and select Measurement).
These symbols are displayed if access lock is active:
IS-Display
– “crossed hand” symbol is displayed in the upper left corner
IG-Display and IG-NT
– lock symbol is displayed in the upper right corner
InteliVision
– “crossed hand” symbol is displayed in the upper right corner of the Status bar
