within the wait band around the set point (i.e., SP
± wait band). In the
pre-ceding diagram, the timer will be stopped between the start and (1), (2) and
(3), and (4) and (5) and will measure the time only between (1) and (2), (3) and
(4), and (5) and the end.
Note: If the wait band is configured to OFF, the wait band will be treated as
infinity and the timer will measure time continuously after changing
from RSET to STRT.
Operation at the Program End
Display at the Program End
When the program ends, the process value will be displayed on the No. 1
display (refer to Note below) and the set point and End will be alternately
displayed on the No. 2 display at 0.5 second intervals.
Note: One of the following displays: PV/SP, PV only, or PV/MV.

Program End Output
In the case of 900-TC8 and 900-TC16, When the Program Pattern parameter
is changed from OFF to STOP or CONT, the Auxiliary Output1 Assignment
parameter will automatically be configured to the END output. When the
Program Pattern parameter is changed from STOP or CONT to OFF, the
Alarm 1 Output Assignment parameter will automatically be initialized to
ALM1. The output assignment parameters can also be used to assign the
program END output to any output.
In the case of 900-TC32, When the Program Pattern parameter is changed
from OFF to STOP or CONT for the 900-TC32, the Auxiliary Output 1
Assignment parameter will automatically be set to the END output. When the
Program Pattern parameter is changed from STOP or CONT to OFF, the
Alarm 1 Output Assignment parameter will automatically be initialized to
ALM1. When using heating/cooling control and the Program Pattern
parameter is changed from OFF to STOP or CONT, the END output will not
be assigned to an output. Use the output assignment parameters to assign the
program END output to the desired output.
