Chromalox TEMPERATURE CONTROLLER 1604-7 - Manual (Page 17)

The configuration procedure is completed and the
instrument shows "
-.-.-.-.
" on both
displays.
If no other setting is necessary, push the FUNC
pushbutton, the display returns to show "COnF".
Otherwise access to the advanced configuration
parameter proceeding as follows:
1) using
s and t pushbuttons to set the 262
code on the display.
2) push the FUNC pushbutton.
P18 = Main control output action
This parameter is skipped if none of the outputs is
configured as control output.
nOrL = the power output is equal to the result of
PID calculation.
CnPL = the power output is complemented (100 -
PID calculation).
P19 = Displayed value of the main power
output
This parameter is skipped if none of the outputs is
configured as control output.
nOrL = the displayed value is equal to the result
of PID calculation.
CnPL = the displayed value is complemented
(100 - PID calculation).
P20 = Secondary control output action
This parameter is available only when two control
outputs are configured.
nOrL = the power output is equal to the result of
PID calculation.
CnPL = the power output is complemented (100 -
PID calculation).
P21 = Displayed value of the power output
for the secondary control output
This parameter is available only when two control
outputs are configured.
nOrL = the displayed value is equal to the result
of PID calculation.
CnPL = the displayed value is complemented
(100 - PID calculation).
NOTE: when two control outputs are configured, the
P18 and P19 selections are applied to the "rEv"
control output while P20 and P21 selections are
applied to the "dir" control output.
P22 = Cooling media.
Available only when the device is configured with
two control outputs.
AIr = Air is used as cooling media.
OIL = Oil is used as cooling media.
H2O = Direct water is used as cooling media.
Changing P22 parameter, the instrument forces
the cycle time and relative cooling gain param-
eters to the default value related with the chosen
cooling media
When P22 = AIr
- Cyx = 10 s and rC = 1.00
P22 = OIL - Cyx = 4 s and rC = 0.80
P22 = H2O - Cyx = 2 and rC = 0.40
Where Cyx is the cycle time(Cy2 or Cy3) of the
out programmed as "dir" control output.
P23 = Relative cooling gain calculated by
SMART function.
Available only when device is configured with two
control outputs.
OFF = SMART algorithm does not calculate the
rC parameter value
On = SMART algorithm calculates the rC
parameter value.
