3.15 Indication at the discharge of test objects
Important: Have attention to chapter 2.14 and 2.15.
If the test voltage is off, the test object is discharged by the tester au-
tomaticly. The integrated residual voltage detection is monitoring the
discharge process. If the residual voltage under-runs 60 V, the discharge
process is finished.
As long as the discharge process is
active, the red button "RESET" and the
red lamp of warning-set is active. The
digital output HV-ON (X7 pin 9) is hold-
ing "high".

3.14 SAFETY CIRCUITS SK1 and SK2
The high voltage device is equipped with two safety circuits. Op-
eration with a second safety circuit increases the safety on test
systems with guards.
ONLY AN ELECTRICIAN IS ALLOWED TO WORK ON THE SAFETY
CIRCUIT, WITH THE DEVICE ELECTRICALLY ISOLATED FROM THE
MAINS (UNPLUG FROM THE MAINS SOCKET).
Attention:
Faulty safety circuits are only allowed to be repaired by an electrician with
appropriate skills.
Attention:
The managerial staff must ensure the safety circuit works correctly, on
site, immediately after the completion of the repair.
Note:
SK1 is closed by connecting to Ue
SK2 is closed by connecting to GND

3.14.1 Fault in the device‘s safety circuit
Important: If a malfunction is found in the safety circuit incorporated in
the device, testing must be interrupted immediately. No further tests are
allowed. The device must be sent to ELABO for repair without delay.
