Operating Instructions CORREX
7.1.3 Installation of the CORREX
1. Empty the storage tank, if necessary.
2. For retrofitting, remove the old protective (Mg) anode, if any.
3. Screw the titanium anode with preassembled screw fitting (1) down into the
threaded sleeve of the storage tank until it is pressure-tight.
Note: Depending on the design, the G 3/4" screw fitting is equipped with a
PTFE sealing. When this sealing is damaged, for instance, after having been
screwed down repeatedly, the joint must be resealed with sealing material
for threads like hemp or PTFE ribbon.
4. Push the spade terminal (7) at the end of the cable labelled 'connection
ground tank' under the earthing screw (8) of the tank. If the tank has no
earthing screw, the ground contact must be established by other reliable
means. Without a perfectly conducting galvanic connection, the CORREX
UP system cannot perform its function.
5. Push the receptacle at the tank end of the connecting cable (4) on the tab
(5) at the toothed disk of the anode (6).
6. Push the two-pole connector at the other end of the connecting cable on
the connectors in the opening (10) of the plug-in potentiostat. Point the
guide lug upwards; this orientation is the only way to fix the two-pole plug
in the housing of the plug-in potentiostat without using force.
7. Fill the storage tank with water and check for leaks.
8. Observe the pilot lamp in the plug-in housing.
9. Required function check: The correct polarity must be checked by
measuring magnitude and sign of the drive potential applied with a
DC-voltmeter (e.g. digital multimeter or CorroScout
the instrument must be set to the 20 V DC range, the negative probe of the
instrument connected to the tank and the positive probe to the titanium
anode. The drive potential applied must be U > +1.9 V DC. Observe the '+'
sign. For this measurement, the tank must be filled with water and the
plug-in potentiostat connected.
Note: The CORREX
tank has been filled with water.
On top pilot lamp (11) green: mains supply established and CORREX
MP 1.9-900 ready to operate.
Pilot lamps (11) off: probably no mains voltage.
Lower pilot lamp (11) red: malfunction of the system. In this case, the
checks described in chapter 9 must be performed.
Note: If the pilot lamp shines right away after the first installation, it can
be assumed that the malfunction is due to inappropriate installation.
Check and eliminate the fault in accordance with the instructions set out
in chapter 9.
