An error code will be displayed, and the tripping alarm output will operate
when a branch output is cut off.
Other Status Monitoring The internal temperature and replacement time status are monitored and
error processing is performed if an error is detected.
Operation in Setting
Mode
Setting Mode can be used to set the various parameters. The S8AS is in oper-
ating status when it is in Setting Mode. Branch outputs are connected in Set-
ting Mode in the same way as in Run Mode. When an error is detected,
branch outputs will be cut off and alarms will be output, just as they are in Run
Mode.
Note If an error occurs in Setting Mode, the error code is not displayed.
Operation in Test
Mode
In Test Mode, each branch output can be set to ON or OFF (connected or dis-
connected).
The factory default setting for all outputs is ON, so any branch outputs that are
not being used must be turned OFF in Test Mode.
In Test Mode, the operation of each branch circuit can be verified as well as
the operation of the startup sequence and shutdown sequence.
Note (a) If the power is turned OFF while the S8AS is in Test Mode, the
S8AS will enter Test Mode again the next time that the power is
turned ON.
(b) When an error occurs in Test Mode, branch outputs will be cut off
and external signals will be output, just as they are in Run Mode.
The error code will not be displayed.
(c) Refer to 7-3 Clearing Errors for details on clearing errors.
Note (1) When the S8AS is shipped from the factory, all branch outputs are set to
ON (connected) and the S8AS will enter Run Mode when the power is
turned ON. After setting the parameters that require changing, switch to
Test Mode, set the switching status of the required branch outputs, and
then switch to Run Mode.
(2) If a branch output is OFF (disconnected) when the mode is changed from
Test Mode to Run Mode, it will not be connected (ON) in Run Mode.
(3) If the power is turned OFF while the S8AS is in Test Mode, the S8AS will
start in Test Mode the next time that the power is turned ON, but all
branch outputs will be OFF.
