Alarms stays in Alarm list even though Fault reset was used to
acknowledge them
Problem:
Fault reset was used to acknowledge active alarms displayed by controller, but alarms stayed
in alarm list after they became inactive, because controller does not allow an alarm to be
acknowledged by pressing the fault reset button while the alarm is still active. It is caused by
setpoint
Engine protect
:
ResetActAlarms
setting to DISABLED. This is a new option which
was not available in IG/IS classic
– you can now disable resetting of alarms that are currently
active by setting the setpoint to DISABLED (Marine authorities requirement).
Solution:
If you don’t need this functionality, switch the setpoint to ENABLED, which is the mode
compatible with IG/IS classic controllers.
No active call after some protection has been activated
Solution:
a) Setpoint that enables active calls for a particular protection type is not set to ENABLED.
Check it in
Act. calls/SMS
setpoints group.
b) Setpoint
Act. calls/SMS
:
AcallCHx-Type
is set to a wrong option. E.g. it is set to SMS-GSM,
while analog modem is actually connected. You have to change this setpoint to such option
that matches used type of connection.
c) Phone number or e-mail address is wrong. Check the setting (
Act. calls/SMS
:
AcallCHx-Addr
setpoints), including the prefix codes for local phone calls or intercity calls.
Forgotten controller password
Solution:
a) For all users, except the user 0 = administrator, password can be reset by the administrator. If
administrator is logged in, he can set password to any value for a particular user. Controller
panel or PC can be used to do that:
Controller panel
: log in as administrator (default user name of the administrator is U0), go to
Users/Password in the menu and select user for which you intend to reset the password. You
will see “Reset password” option on the screen, select it, press Enter to confirm your choice
and press Esc to get back into the menu. Now that user has password set to
“0” and it can be
set to any value.
PC SW (InteliMonitor)
: log in as administrator (default user name of the administrator is U0),
go to menu Monitor / Admin users. A window opens where you can set up access rights etc.
Select the user for which you intend to reset its password and press the crossed lock icon in
the upper left corner. You can also reset passwords for all users at once. Password is set to
“0” and it can be set to any value.
b) If the highest (level 7) administrator password is lost, you need to provide your distributor this
information: controller serial number and PasswordDecode number.
Serial number and PasswordDecode number are available in InteliMonitor in Monitor /
Controller/Archive info... Both serial number and PasswordDecode number are available on
controller Info screen 2. Hold Enter and push the Esc button to enter the screen on IS-Display,
push the right arrow then to display information on IG-NT / IM-NT screen.
PID regulator doesn't work in the same way as in IS-CU
Solution:
a) If the PID regulator in internal PLC of the controller doesn't behave in the same as you were
used to with the classic IS-CU controller, set the parameters 10 times higher than for the PID
regulator in classic IS-CU.
MCB fail / GCB fail alarm is issued after switching controller on
Problem:
Breaker fail alarm is issued if a breaker feedback signal is not connected directly to a
controller and controller receives information about breaker state after initial reading of its
binary inputs. This happens if breaker feedback is evaluated in controller PLC or it is
connected to controller via an extension module (standard or virtual).
