Controller interface

Setpoints setting cannot be changed

Solution:
a) Setpoints are password protected and password is not entered. Go to menu ->
Users/Password and log in. If your user profile has sufficient access rights, setpoints editing
will be unblocked. System administrator can change controller configuration to give you
access to setpoints.
b) Password is entered (= user is logged in), but setpoints cannot be changed. That means these
are probably blocked by some higher protection level than the current user has got. You need
to log in as a user with sufficient access rights or contact system administrator to give you
access to setpoints.
c) Access lock function is active. Switch the Access lock function off.

Controller does not react to buttons pushing

Problem:
Controller does not react to Start, Stop, Fault & Horn reset, GCB, MCB, MGCB or controller
mode ←,→ buttons pushing.
Solution:
a) Controller is not in MAN or SEM (IS-NT only) mode, switch it to one of these modes. See
OFF-MAN-AUT-TEST mode chapter in IGS-NT-x.y-Reference Guide for information which
buttons works in a particular mode. For example GCB, MCB, Start and Stop buttons does not
work in the AUT mode.
b) There are active alarms in controller alarm list. Button function can not be performed because
of an alarm activity. Get rid of an alarm first and use a button again.
c) Setpoint Basic settings: Local buttons is set to position EXTBUTTONS, which means that
only external control using binary inputs is enabled. Set this setpoint to position PANEL or
BOTH to be able to control genset using its panel buttons.
d) Access lock function is active. Switch the Access lock function off.

Controller mode cannot be changed

Problem:
Controller mode cannot be changed,
Solution:
a) The Basic settings: ControllerMode setpoint is password protected and password is not
entered. Go to menu -> Users/Password and log in. If your user profile has sufficient access
rights, setpoint will be unblocked. System administrator can change controller configuration to
give you access to commands and setpoints.
b) Function for controller mode forcing is active. Go to Measurement IO / Binary inputs and
check if binary input with Remote OFF, Remote MAN, Remote AUT or Remote TEST function
is active. If present and active (check also input polarity using GenConfig – input function can
be inverted), controller mode cannot be changed from mode selected with a binary input
function. It is necessary to change binary input state or disconnect binary inputs from
controller to be able to change controller mode. There may not be binary input with one of the
above mentioned functions.
