Operating instructions
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 39.
Perform the following work steps:
1.
Close the inflow tap (Fig. 1 “Water sampling station EASYPRO
COMPACT” on page 8, pos. 8) 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
sample water supply back on externally. It starts the measurement
and regulation.
ü
The EASYPRO COMPACT water sampling station has been
successfully shutdown temporarily and put back into operation
again.
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. 1 “Water sampling station EASYPRO
COMPACT” on page 8, pos. 8) 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 connections from the inflow tap and from
the sample water filter (Fig. 1 “Water sampling station EASYPRO
COMPACT” on page 8, pos. 9), as well as the outgoing hose
connection from the outflow tap (pos. 4).
5.
Unscrew the temperature sensor (pos. 5) from the station, open the
extraction point and bleed the water from the water sampling station.
6.
Now immediately take the measuring cells out of the valves and store
them stood upright in a 3-molar potassium chloride solution.
