3.2.3 Indication of Operating States
Signal Lamps at the High-Voltage Module
The signal lamps integrated into the high-voltage module indicate
two different operating states:
Green: Test instrument ready for use
• Key switch is in the “I” position (ON).
• Power supplies for signal and control circuits at the
high-voltage module are switched on.
• Test voltage supply circuits are still switched off, and are still
secured against inadvertent activation.
Attention!
!
All safety precautions required before entering the dan-
ger zone must now have been implemented, amongst
others: set up WS1 warning signs and ZS2 auxiliary
signs in accordance with DIN 40008, part 3.
Red: Instrument ready for operation, caution: danger!
• The menu for starting the voltage test has been opened, and
the START key has been activated.
• The power supply circuit for the safety test probe is still
switched off, assuming the trigger has not been pulled at the
high-voltage pistol.
• The test probes are secured against inadvertent contact, as-
suming the triggers at the high-voltage pistols have not been
pulled.
Attention!
!
All means of access to the danger zone must be closed
when the high-voltage module is in the “standby” mode!
The device must be sent to GMC-I Service GmbH in order to
replace lamps.
External Signal Lamps (feature F1)
The external signal lamps indicate the same operating states as
the signal lamps integrated into the high-voltage module. They
provide additional security at the test site, and must be plainly vis-
ible beyond the boundaries of the danger zone.
The external signal lamps can only be connected to the 12 V/5 W
output jack at the high-voltage module (feature B1 or B2).
Note
For reasons of safety, only Z504D signal lamps available
from GMC-I Messtechnik GmbH may be used.
