5.3 S1 745 SETUP 5.3.1 DESCRIPTION
Settings to configure the relay are entered on this page. This includes passcode security, user preferences, the
RS485/RS422 communication port, the internal time and date, default messages, and various commands.
5.3.2 PASSCODE
After installing the setpoint access jumper, a passcode must be entered (if the passcode security feature is
enabled) before setpoints can be changed. When the 745 is shipped from the factory, the passcode is
defaulted to
0
. When the passcode is
0
, the passcode security feature is disabled and only the setpoint access
jumper is required for changing setpoints from the front panel. Passcode entry is also required when program-
ming setpoints from any of the serial communication ports.

This message cannot be edited directly. It indicates whether passcode
protection is enabled (

).
RESTRICT SETPOINT
WRITE ACCESS? No
Range: No / Yes
This message is only displayed when setpoint write access is allowed and
the current passcode is not
0
. Select
Yes
and follow directions to restrict write
access. This message is replaced by
ALLOW SETPOINT WRITE ACCESS?
when
write access is restricted.
ALLOW SETPOINT
WRITE ACCESS? No
Range: No / Yes
This message is only displayed when setpoint write access is restricted.
New setpoints cannot be entered in this state. To gain write access, select
Yes
and follow directions to enter the previously programmed passcode. If
the passcode is correctly entered, new setpoint entry is allowed. If there is
no keypress within 30 minutes, setpoint write access is automatically
restricted. As an additional safety measure, the following minor self-test error
is generated when the passcode is entered incorrectly three times in a row:
SELF-TEST ERROR: ACCESS DENIED
CHANGE PASSCODE?
No
Range: No / Yes
Select
Yes
and follow directions to change the current passcode. Changing
the passcode to the factory default of
0
disables the passcode security
feature.
ENCRYPTED PASSCODE:
AIKFBAIK
Factory default passcode: 0
If the programmed passcode is unknown, consult the factory service
department with the encrypted passcode. The passcode can be determined
using a deciphering program.
