N N o o t t e e : : Many faults can be located and rectified directly on the system by mea-
suring DC voltage and current, polarity, insulation and resistance. The neces-
sary measuring techniques are described in chapter 9.2. Disconnect any
installed electrical tubular heating elements from the mains supply. The chek-
ks described may o o n n l l y y b b e e p p e e r r f f o o r r m m e e d d b b y y a a n n e e l l e e c c t t r r i i c c a a l l f f i i t t t t e e r r o o r r b b y y q q u u a a l l i i f f i i e e d d a a f f t t e e r r - -

Fault message: p p i i l l o o t t l l a a m m p p o o f f f f
Possible cause: absence of mains voltage.
Remedial action: ensure continued supply of mains voltage.
Fault message: p p i i l l o o t t l l a a m m p p f f l l a a s s h h i i n n g g r r e e d d
Preventive action before performing any other checks: reset the potentiostat
by separating the device for about 30 seconds from the mains supply in order
to create well-defined starting conditions. Reconnect the mains supply.

causes and perform the measures required as remedial action.
1. The hot-water tank is not filled with water.
Inspection: Check that the hot-water tank is filled completely with water.
Remedial action: if necessary, fill the hot-water tank completely with water.
2. The electrical contact between plug-in potentiostat and anode / tank
connection by means of the connecting cable is not ensured.
Inspection: Check all connections and contacts for perfect electrical continuity.
Remedial action: establish the electrical contact and install a new
connecting cable, if needed.
