Installation and operating instructions
6. Start
(continued)
Programming
The controller on the basic vessel is to be programmed depending on the confi guration and system.
- Flexcon Control Unit, M-K/S.
The required procedure and possible setting changes can be found on page 21; 22;
menu programming mode.
Note: The active errors displayed after switching on the controller: min. water level; min.
pressure alarm are logical. After switching to programming mode, the control
for expansion (fi lling) is passive. Changed parameters become active when operating
mode is reselected.
- Remove unpermitted loads (supported objects, lateral loads) from the basic vessel.
- Perform the zero adjustment during operation. This prsocedure corrects deviations from test
tolerances when installing the basic vessel and sets the levelparameter to 0%.
- Change the preset nominal system pressure (2 bar) to the permitted project value (note).
Note: Start and system temperature, page 12; §. 1.
- Other parameters must be programmed depending on system requirements.
- If 2 systems are operated in parallel, this setting must be performed after installation of the
RS485 data cable. The controller programmed fi rst is the Master.
Other measures, settings, changes are to be carried out identically, per controller.
The service programming mode and the factory programmed presets can be found on
page 22, the operating displays on page 20, Operating mode menu.
- SDS controller, M-K/U.
The required procedure and possible setting changes can be found on page 28; 29;
Menu programming mode.
Note: The active errors displayed after switching on the controller: min. level alarm limit,
min. pressure alarm limit are logical. The controller is also active for expansion (fi lling)
after the code has been entered (programming mode).
Changed parameters become immediately active after being saved.
- Remove unpermitted loads (supported objects, lateral loads) from the basic vessel.
- Perform the zero adjustment during operation. This procedure corrects deviations from test
tolerances when installing the basic vessel and sets the level parameter to 0%.
- Change the preset nominal system pressure (2 bar) to the permitted project value (note).
Note: Start and system temperature, page 12; para. 1.
- Other parameters must be programmed depending on system requirements.
The identifi cation of start enables traceability, which also enables a time-dependent
diagnosis of the installed SDS- Module 32, timer, operating hours counter **
(errors, SDS- Module 43, analogue modem connection **).
The service programming mode and the factory programmed presets can be found on
page 30, the operating displays on page 27, Operating mode menu. [ Specifi cation of menu
lines (F5; F7a 1; 2; G7a 2; G8a 1) in the terminal diagrams, page 32; 33; 35, refers to the
required change to presets during upgrades (**).]
The completed programming procedure (electrical installation) makes the compressor expansion
automat electrically ready for operation.
Start and system temperature.
The installed, hydraulic compartment of the expansion automat is to be fi lled as far as the shutoff
device on the expansion pipe, depending on the condition of the heating system.
All present shutoff devices must now be opened.
- Installation of the water prefi ll for a non-operational, cold heating system.
The basic vessel or all vessels with a common expansion controller (collective pipe), must be
fi lled with water before opening the shutoff device to the expansion pipe.
From practical experience, the quantity of this water is ...20%... of the vessel capacity. This
value takes into consideration losses and a lower vessel level as a consequence of reduced gas
quantities after a heated heat generating system.
(Filling example 1)
- Set the nominal expansion capacity for operated, hot heating system.
The basic vessel or all vessels with a common expansion controller (collective pipe), are to be
fi lled with the nominal expansion capacity from available system temperature including the
water prefi ll, before opening the shutoff device to the expansion pipe.
To calculate this quantity, the design data for the nominal vessel size or the total of the
nominal vessel sizes and the actual values of the heating system are required. Use the following
example as the basis for your own calculation.
Vset = [(
Dn
’act × 80% ) /
