6-20 TOS5051A/5050A
6.3 Remote Control
• Be extremely careful when operating the tester in the remote control mode
in which the dangerous high test voltage is ON/OFF-controlled remotely.
Provide means to assure that the tester does not enter the TEST-ON state
(state that the test voltage is being delivered) by inadvertent operation.
Provide means to assure that none can touch the DUT, test leads, probes,
output terminals and their vicinities when in the TEST-ON state. When any
of these protective functions are unavailable, do not attempt to control the
tester remotely.
• To those using the old model TOS5050/5051
The
Interlock signal input pin assignments are different from the old model TOS5050/
5051. Therefore, the 14-pin Amphenol plug that is supplied with the tester cannot be
shared between the new and old models. See Table 6-2 and Fig. 6-3.
6.3.1 Remote Control through the REMOTE Connector
The REMOTE connector is used to turn the high voltage ON/OFF according to the
signal received from the optional remote control box (RC01-TOS or RC02-TOS) or
the high voltage test probe (HP01A-TOS and HP02A-TOS).
Control procedure
1. Turn OFF the POWER switch.
2.
Use a dedicated cable (5-pin DIN cable) to connect the REMOTE con-
nector on front panel to the optional device.
3. Turn ON the POWER switch.
The “REMOTE” message appears, the start input from the optional device is
enabled, and the START switch on the panel is disabled. However, you can
stop the voltage both from the STOP switch on the panel and the stop input
from the optional device. For details, see the operation manual for the optional
device.
Reverting to panel control
1.
Turn OFF the POWER switch.
2.
Remove the dedicated cable (5-pin DIN cable) from the REMOTE con-
nector on the front panel.
3.
Turn ON the POWER switch. The “REMOTE” message disappears and
the START switch on the panel is enabled.
