The Key Switch
The key switch protects the instrument against unauthorized use.
Keep the key in a safe place to which only authorized personnel
have access.
Each time testing is completed, turn the key to the “0” position
and remove it from the lock.
3.1.3
Indication of Operating States
Signal Lamps
The signal lamps integrated into the high-voltage module indicate
the two different operating states:
Green
:
Stand-By State
• Key switch is in the “I” position (on).
• Power supply to signal and control circuits at the
high-voltage module is switched on.
• All test voltage circuits are switched off and are secured
against inadvertent activation.
!
Attention!
All safety precautions which are required before entering
the danger zone should now already be implemented,
including posting of warning signs (WS1) and additional
signs (ZS2) in accordance with DIN 40008, part 3.
Red
:
Ready for Activation,
Caution: Danger!
• The menu used to start the voltage test has been opened and
the start key has been activated.
• No voltage has yet been applied to the safety test probe,
assuming the trigger at the high-voltage pistol has not been
pulled.
• The test probes are secured against unintentional contact,
assuming the triggers at the high-voltage pistols have not been
pulled.
!
Attention!
When the instrument is “ready for activation”, all points of
access to the danger zone must be secured!
See chapter 11.5.2, page 67, regarding signal lamp replacement.
External Signal Lamps
The external signal lamps indicate the same operating states as
the signal lamps integrated into the high-voltage module. They are
used for additional security at the measuring site, and must be
plainly recognizable beyond the boundaries of the danger zone.
The external signal lamps can be directly connected to the
respective terminals at the high-voltage module.
Note
For reasons of safety, only Z504D signal lamps by
GMC-I Messtechnik GmbH may be used.
See chapter 11.5.3, page 68, regarding signal lamp replacement.
