2.3 Reset of System
There are three types of Reset:
-
Power Up Reset
-
Hardware Reset
-
Reset to Default
Attention
All of the above resets will switch off all gas flow controllers.
If the device refuses to come up on power on, press button <8> while switching the
device on in order to perform a total reset (equal to First Start Reset). This problem can
have 2 reasons:
-
Data in memory was destroyed through a transient. The described procedure will fix
this problem.
-
There is an error in the hardware. If the Start Up problem occurs more than once
contact your local MKS service center.
Power Up Reset is performed every time the system is switched on. It resets all data which are
needed
for
system
administration.
Data
of
process
parameters
are
not
affected.
Hardware Reset is similar to Power Up Reset. It is triggered by the keys <OFF> and <cursor right>
pressed at the same time. In any case Power Up or Hardware Reset leads to the MAIN MENU.
Reset to Default sets all process parameters to their default value. This reset is
triggered in SYSTEM SETUP menu.
After the device has been turned off, one should wait for ca. 15 seconds before turning it on again.
2.4 Display adjustment
The viewing angle of the LCD display and the timeout setting of its back light saver, may be set in
SYSTEM BACKUP menu.
