7.4 Checking the alarms
The final step in commissioning is to check the alarms. The
system must be in operating state "Automatic".
To shorten the duration of the checks, the alarm times can be
reduced to 5 seconds. Note down the actual values before
changing them. The values can be changed via the following
menus:
•
8.5.10
Settings cell line
• 8.5.13
Settings rectifier
• 8.5.16
Settings tank level
• 8.5.33
Settings alarm delays
.
7.4.1 Degassing and storage tank
Checking the alarm for level switch (4.03)
This level switch indicates a leakage of the degassing and
storage tank.
1. Make sure the system is in operating state "Automatic".
2. Put level switch (4.03) into a flat container filled with 5-10 mm
of water.
3. The alarm is triggered on the Selcoperm display and the
system switches to operating state "Stop" immediately without
any stop delays.
4. Take the level switch out of the container and dry the
electrodes with a dry and clean cloth.
5. Acknowledge the alarm on the display.
Checking the alarm for level switch (4.12)
This level switch indicates an overflow of the degassing and
storage tank.
1. Remove the cover of the level switch.
2. Make sure the system is in operating state "Automatic".
3. Press the test button (pos. A3, fig.
31 ).
4. The alarm is triggered on the Selcoperm display and the
system switches to operating state "Stop" immediately without
any stop delays.
5. Reinstall the cover.
6. Acknowledge the alarm on the display.
Checking the alarm for exhaust air flow sensor (4.13)
This sensor measures the air flow in the exhaust air line.
1. Make sure the system is in operating state "Automatic".
2. Reduce the air flow via the speed adjusting knob on the
degassing fan until the minimum level is undercut. See
section
8.5.15
Overview tank
.
3. The alarm is triggered. The system stops the different
components with certain time delays. For details see section
8.5.35 Start and stop delays .
4. Acknowledge the alarm on the display.
5. Push [
]. The system switches back to operating state
"Automatic".
6. Set the air flow via the speed adjusting knob on the degassing
fan according to the setpoint. See section 5.2.4 Setpoints .
7.4.2 Selcoperm electrolyser
Check the soft water flow alarm
1. Make sure the system is in operating state "Automatic".
2. Slowly close water inlet valve (V0.01) until the minimum flow
rate is undercut. See section 8.5.7
Overview cell lines
.
3. The alarm is triggered. The system stops the different
components with certain time delays. For details see section
8.5.35 Start and stop delays .
4. Open water inlet valve (V0.01).
5. Acknowledge the alarm on the display.
Check the maximum voltage alarm
1. Change the maximum voltage value to the minimum value.
See section 8.5.13
Settings rectifier
.
2. Make sure the system is in operating state "Automatic".
3. The alarm is triggered. The system stops the different
components with certain time delays. For details see section
8.5.35 Start and stop delays .
4. Acknowledge the alarm on the display.
5. Reset the maximum voltage to the original value.
Check the minimum voltage alarm
1. Change the minimum voltage value to the maximum value.
See section 8.5.13
Settings rectifier
.
2. Make sure the system is in operating state "Automatic".
3. The alarm is triggered. The system stops the different
components with certain time delays. For details see section
8.5.35 Start and stop delays .
4. Acknowledge the alarm on the display.
5. Reset the minimum voltage to the original value.
The alarm values must be reset to the previous
values or to the default values after the alarms have
been checked.
