5.2. CONTINUITY - FOUR WIRE METHOD (R
PE-4WIRE
)
Complying with EN 60204-1, continuity of protective bonding circuit between PE terminal and
relevant points of the protective conductor system must be checked by injecting a measurement
current of 0.2 A up to 10 A approx.
Limit values are the values which correspond to the length, cross section and material of measured
conductor.

LIMIT
touch-screen key to select limit mode (STANDARD, 60204 SET Z or 60204 SET L).
Currently selected value (STANDARD mode) or CALC (60204 SET Z or 60204 SET L mode) is
displayed on the bottom of the key. CALC message means the value is calculated.
6 .....
MODE
touch-screen key to select operation mode (MANUAL or TIMER). Currently selected mode
is displayed on the bottom of the key. TIMER mode is available only if STANDARD limit mode is
selected.
