6. INTERFACES
6.2.5.2 INPUTS
A „High“ signal on a digital input on the digital interface can be achieved
in two different ways.
• Connect the auxiliary vUe (X7, Pin22) to the related
input.
• Apply an external auxiliary voltage of +24 V DC to the related in-
put pin. However, in this case the ground for this supply voltage
is to be connected to GND (X7, pin 17).
An open (digital-) input is recognized as LOW.
Note delay-time: Between the reset-operation of an input and a follow-
ing set operation of an other input, a minimum delay-time of 100 ms must
exist (reaction time of the electronic, relay setting, ...).
„Set HV“ Start an HV test:
The connection of pin 2 to +Ue (or an external supply voltage) will apply
the high voltage. The signal can be present as pulse of 100 ... 500 ms,
preferably.
Note: A „set“ using this interface is only accepted if the device is in the
remote control mode (pin 4 connected to +Ue, see Remote control mode)
Pin 2 Set HV
„Reset HV“ Interrupt or switch off a HV test:
The connection of pin 3 to +Ue (or an external supply voltage) interrupts
a high voltage test started, or clears an error that has occurred previously.
The signal can be present as pulse of 100 ... 500 ms, preferably.
A
reset
signal always has priority over a
set
signal.
Note:
A reset using this interface is only accepted if the device is in the
remote control mode (pin 4 connected to +Ue, see Remote control mode).
Pin 3 Reset HV
„Remote“ control mode:
The device is placed in the remote control mode by connecting pin 4 to
+Ue (or an external supply voltage). Only then is it possible to control the
high voltage tester using the digital interface.
