Operation
De gassing 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 M a nual 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.
" S E" 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 (see chapter 7.6 "Vacuum test" on page 33) and test runs during
service work (see chapter 9.3 "Inspecting system degassing and make-up
degassing" on page 39 ).
" NE" make-up degassing of the fill and make-up water
The make-up degassing is required for test runs during service work (see
chapter 9.3 "Inspecting system degassing and make-up degassing" on page 39)
and in the "Magcontrol" mode when filling the entire system with water.
• "Next" and "Back" buttons
– Selecting "NE" or "SE".
• "Auto" button
– Return to Automatic mode.
8.1.3 S top 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 S ummer 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, see chapter 8.2.1 "Customer menu" on page 36 .
S e lection 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!

8.1.5 Re starting
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
De vice 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).
