SS SETPOINTS
SS S1 745 SETUP
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.

Range: Cannot be edited
This message cannot be edited directly. It indicates whether passcode
protection is enabled (Read Only) or disabled (Read & Write).
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.
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
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.
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.
