10 Shutdown
10.1 Short-term shutdown
Short-term shutdown involves deactivation for the calibration of the
measured values or for maintenance work, for example. For long-term
shutdown, see section 10.2 „Long-term shutdown“ on page 44.
Perform the following work steps:
1.
Close the inflow tap (Fig. 2 „Water sampling station EASYPRO 4“ on
page 10, pos. 5) of the water sampling station or switch off the
sample water supply externally. This interrupts the measurement and
the control of the
TOPAX
®
MC
controller, and the sample water circuit
can be opened.
2.
Disconnect the
TOPAX
®
MC
controller's external power supply.
3.
Perform the planned work on the water sampling station.
4.
Reconnect the
TOPAX
®
MC
controller's external power supply.
5.
Open the inflow tap of the water sampling station or switch the sam-
ple water supply back on externally. It starts the measurement and
regulation.
ü
The water sampling station was deactivated and re-activated
(short term).
10.2 Long-term shutdown
This section describes the required actions in the event of long-term shut-
down in order to ensure the functionality of the water sampling station.
Perform the following work steps:
1.
Close the inflow tap (Fig. 2 „Water sampling station EASYPRO 4“ on
page 10, pos. 5) of the water sampling station or switch off the
sample water supply externally. This interrupts the measurement and
the control of the
TOPAX
®
MC
controller, and the sample water circuit
can be opened.
2.
Disconnect the
TOPAX
®
MC
controller's external power supply.
3.
Pinch off all cables in the
TOPAX
®
MC
controller.
4.
Uncouple the ingoing hose connection from the inflow tap and from
the sample water filter (Fig. 2 „Water sampling station EASYPRO 4“
on page 10, pos. 3), as well as the outgoing hose connection from
the outflow tap (Fig. 2 „Water sampling station EASYPRO 4“ on page
10, pos. 12) and the measuring cell valve.
5.
Unscrew the black screw caps from the underside of the valves and
allow the sample water to drain out of the valves.
6.
Now immediately take the measuring cells out of the valves and store
them stood upright in a 3-molar potassium chloride solution.
ü
