OPERATION PROCEDURE
21
3.5 Remote Control
1) Remote-control with the option
The START/STOP operation of the Tester can be remote-controlled with the remote control box
(optional).
As the plug of the remote control cable is connected to the REMOTE control connector on the
Tester front panel, the internal circuit is automatically switched to the remote operation mode. In
this case, the START switch on the Tester front panel is disabled, although the stop operation can be
done either at the Tester front panel or at the remote control box.
2) Remote-control by the other control system
The Tester can be remote-controlled by other control system equipment without using the remote
control box.
A 5-pin connector as per the DIN standard is required for the following operation. If it is dif
fi
cult to
obtain a DIN connector, contact your Kikusui agent/distributor.
•
Be extremely careful when using this method because the high voltage is on/off -
controlled with an external signal. Pay attention so that the high test voltage is not
generated inadvertently. Also, provide full measures to ensure that nobody is con-
tacted with the high voltage areas (DUT, test lead-wire, probe or output terminal
etc.) when the test voltage is being delivered. When these measures are unavail
-
able, do not use the following remote control method.
■
REMOTE control connector
To use the Tester in remote control mode, the pin No.2 and No.3 of connector must be externally
connected.
By controlling the START and STOP contacts shown in Fig.3-4, test voltage can be on-off con-
trolled in the same manner as done at the Tester front panel. However, when the FAIL ALARM of
TEST MODE switch on the rear panel is OFF. For details, refer to "3.7 Special Test Modes" on
page 26.
Fig.3-4
In the case of the setup shown in Fig.3-5, the test voltage is turned on when the switch is thrown to
the NO position, and Tester is forcefully reset when the switch is returned to the NC position.
However, when the FAIL ALARM of TEST MODE switch on the rear panel is OFF. For details,
refer to "3.7 Special Test Modes" on page 26.
