Operation
Degassing the make-up water
Is automatically activated for every make-up
during continuous or interval degassing. The
corresponding setting must have been made in
the Customer menu.
The 2-way motorized ball valve switches the
volume flow from system to make-up water.
The process is the same as in continuous
degassing. If the system water is not to be
degassed or if the system is in Summer
operation with circulating pumps shut down If
the, you can activate the make-up degassing in
the Customer menu.
Activation/setting:
–
Automatic activation for every make-up.
–
Activated from the Customer menu.
–
Degassing time = Make-up time.
8.1.2
Manual mode
Manual mode is intended for test and service tasks.
Press "Manual" at the controller. The Auto LED at the operator panel flashes to
visually indicate that manual mode is active. Manually activate or deactivate the
"SE" system degassing or the "NE" make-up degassing.
"SE" system degassing of the system water
The system degassing process corresponds to the continuous degassing in
Automatic mode. The degassing time, however,
is not automatically limited. This setting is required for the vacuum test during
commissioning ( 7.6 "Vacuum test", 37)) and test runs during service work
( 9.2 "Inspecting system degassing and make-up degassing", 43).
"NE" make-up degassing of the fill and make-up water
The make-up degassing is required for test runs during service work ( 9.2
"Inspecting system degassing and make-up degassing", 43) and in the
"Magcontrol" mode when filling the entire system with water.

8.1.3
Stop mode
Stop mode is intended for commissioning of the Servitec.
Press "Stop" on the controller. The Auto LED at the operator panel extinguishes.
Except for the display of information, the Servitec is non-functional in Stop mode.
Function monitoring is stopped. The "PU" pump is switched off. The system
returns an alarm if the Stop mode is activated for more than 4 hours. If "Floating
alarm contact?" in the Customer menu is set to "Yes", the system outputs the
alarm to the group alarm contact.
8.1.4
Summer operation
The degassing of the network water is not assured if the circulating pumps of the
system are shut down during Summer because gas-rich water cannot reach the
Servitec. In order to save energy, use the Customer menu to set the degassing
programme to make-up degassing. If the Servitec is operated with make-up
degassing during Summer, you must switch to interval or continuous degassing
after the circulating pumps have been activated.
Setting in the Customer menu, 8.2.1 "Customer menu", 40.
Selection from 3 degassing programmes.
•
Continuous degassing
–
For commissioning and repairs.
•
Interval degassing
–
For continuous operation (time-
controlled).
•
Make-up degassing
–
Only for make-up water. The machine
is not degassed.
Note!

Restarting
CAUTION
Risk of injury due to pump start-up
Hand injuries may occur when the pump starts up if you turn the pump motor
at the impeller using a screwdriver.
•
Switch the pump to a zero-volts state before turning the pump at the
fan wheel with a screwdriver.
ATTENTION
Device damage due to pump start-up
Pump damage may occur when the pump starts up if you turn the pump
motor at the impeller using a screwdriver.
•
Switch the pump to a zero-volts state before turning the pump at the
fan wheel with a screwdriver.
After an extended standstill time (the device is de-energised or in Stop mode),
the "PU" pump may jam. For this reason, use a screwdriver to rotate the pump at
the fan wheel of the pump motor before restarting.
Note!
A jamming of the "PU" pump is prevented during operation thanks to
forced starting action (after 24 hours).
