Preparing The Brine Dosing Station (Bds); Checking The System Configuration; Starting Up The System Initially; Adjusting The Manual Valves - Grundfos Selcoperm SES Series Installation And Operating Instructions Manual

7.1.4 Preparing the brine dosing station (BDS)

1. Adjust all manual valves to normal operation.
2. Deaerate the brine dosing station. See separate manual.

7.1.5 Checking the system configuration

Check that the following parameters in the respective menus
comply with the actual system on site:
Configuration of system capacity
• System capacity: 8.5.30
• Number of brine dosing pumps:
system capacity
• Size of degassing and storage tank:
tank volume
• Number of degassing fans:
volume

7.2 Starting up the system initially

Before starting up the system, make sure all checks and
preparations described in section
commissioning have been performed.
The system must only be started up via menu
"System menu > Service menu > Service Cell Lines".
See section 8.5.25
switches into operation mode "Service" as soon as
the menu is opened. This ensures that the DC
current for the electrolysis cells stays switched off
during startup.
During startup, the flow rates for the softened water and for the
brine are adjusted to produce the correct salinity of the
electrolyte.

7.2.1 Adjusting the manual valves

1. Close all manual valves (V0.01, V0.06, V0.07, V0.08, V0.09,
V0.10, V1.01, V2.01, V3.01).
2. Switch all 3-way ball valves (V1.02, V2.02, V3.02) to
production position.

7.2.2 Adjusting the total flow rate

First of all, adjust the total flow rate with softened water (without
brine dosing). See setpoint 7 in section
Calculate the setpoint for a single cell line depending on the
number of cell lines in the Selcoperm electrolyser:

The flow rate is adjusted with the cell inlet adjusting valves
(V1.01, V2.01, V3.01).
1. Open water inlet valve (V0.01).
2. Open solenoid valve (0.05) by pushing the respective symbol
on the display.
– The solenoid valve symbol turns green to indicate that the
solenoid valve is open.
3. Slowly open all adjusting valves (V1.01, V2.01, V3.01)
completely.
4. Adjust the water pressure with pressure reducing valve
(V0.02). See setpoint 3 in section
5. Adjust the flow rate for each cell line with the respective
adjusting valve (V1.01, V2.01, V3.01). The actual flow rate of
each cell line can be read from the display.
6. When the flow is adjusted according to the setpoint, close
solenoid valve (0.05) by pushing the symbol on the display.

7.2.3 Adjusting the brine dosing pumps

The maximum flow rate must be adjusted at the dosing pump.
1. Open brine inlet valve (V0.10).
2. Switch on the dosing pump by pushing pump symbol (3).
