Figure 19: Display of the post-program running time
The valve is switched on and off as described below:
• The program has not reached its end: Valve open. A
coolant curcuits through the condenser unit.
• The program has come to an end: Valve open. Cooling
water continues to flow through the condenser unit in
order to condense any remaining solvent vapors.
• 1 Hour (= post-program running time) after the program
has ended: Valve closed. The cooling water flow stops
as the post-program expires. The duration of the post-
program running time may be determined by the user.
5.9
Post-program running time of the pro-
gram-controlled valve
The setting of the post-program running time is achieved by
simultaneous pressing of the time UP- and DOWN-Keys
for a period of 3 seconds.
The symbol “EC” appears in the temperature display and
the current valid post-program running time is shown in the
time display in hours and minutes.
By pressing on either the DOWN- or UP-key the new
post-program running time for switching the valve may be set.
After 3 seconds, the existing mode terminates and the new
post-program running time becomes effective.
5.10 RS-232 Interface
The unit also is equipped with an RS-232 interface. Up to
now, however, no functions are available for exporting data
from the unit across the RS-232 interface.
