Series 9205 Operations Manual Rev A 45
If it is set for an input, it will preload the timer but wait until it sees the input configured go high before it
starts timing. The options are: On Recipe Opcode ( QUENCH Opcode), Input 1 – Input 31.
Quench Hold Event
This option will determine which event will hold the quench cycle. It is used to hold the quench timer with
an external device. If the input that is configured turns on then the quench timer will go into a hold mode.
The list of possible values is: 0 – 15.
Quench Transfer Time Configuration
This option will allow the user to set what will trigger the transfer from the quench cycle. The options are:
Event 2 Active Time, or Event 1 Active to Event 2 Active.
Cascade Inhibit
Note: This field is only applicable if the controller is in Cascade mode . This will turn cascade control on or
off. When inhibit = enabled, the 9205 functions as a multi-loop controller with three control loops. The
options are: enabled or disabled.
PV Difference Cutback
Note: This field is only applicable if the controller is in Cascade Mode . This is used with the Cascade Lower
Range EOPV and Cascade Upper Range EOPV to limit the absolute % output of the furnace loop. This will
turn the PV difference cutback feature on or off. The options are: enabled or disabled.
Cascade Lower Range EOPV
Note: This field is only applicable if the controller is in Cascade Mode . This is the cascade lower range end
of PV difference. This is used with the PV Difference Cutback and Cascade Upper Range EOPV to limit the
absolute % output of the furnace loop. Between the lower range EPOV and the upper range EOPV, there is
a linear interpolation from 0 to the loop 2 output maximum (usually 100 %) that determines the maximum
% output for the furnace loop. The range is -300 to 10000.
Cascade Upper Range EOPV
Note: This field is only applicable if the controller is in Cascade Mode . This is the cascade upper range end
of PV difference. This is used with the Cascade Lower Range EOPV and PV Difference Cutback to limit the
absolute % output of the furnace loop. Between the lower range EPOV and the upper range EOPV, there is
a linear interpolation from 0 to the loop 2 output maximum (usually 100 %) that determines the maximum
% output for the furnace loop. The range is -300 to 10000.
Example: With the Lower EOPV set to 10 and the Upper EOPV set to 110, if the load PV is 1700 and the
furnace PV is 1710, the full 100% output is available. If the load PV is 1600 and the furnace PV is 1710, the
furnace output will not go above 0%. If the load PV is 1655 and the furnace PV is 1710, the maximum output
for the furnace loop will be limited to 55%: (1710 – 1655)/(110-10) * (1.0).
Multiloop Display
This option allows the user to decide which combination of loops will be displayed on the default status
screen. The choices are:
No display Loop 1, Loop 2 Loop 2, Loop 3
Loop 1 Loop 3 Loop 1, Loop 2, Loop 3
Loop 2 Loop 1, Loop 3
The Return button will return the user to the menu screen.
