1.1 Product Introduction
______________________________________________________________________________________________
Chapter 1
Overview
1.1 Product Introduction
The 3930 is a passive auxiliary tester that is connected to and controlled by
a master unit (the 3153 AUTOMATIC INSULATION/WITHSTANDING
HiTESTER, or a sequencer). The 3930 cannot operate on a standalone
basis.
This auxiliary tester is designed to safely permit testing of multiple locations
with a minimum of connection changes. This unit can output from any
channel high voltage that is input through a high-voltage input cord simply
by turning the internal high-voltage relays on and off. Up to four of these
units can be connected to a single master unit, with each unit identified by a
unique ID.

1.2 Features
______________________________________________________________________________________________
WARNING
In order to prevent electric shock, use voltage to ground that is at or
less than the SELV* on the LOW side of the high-voltage input cords.
Although the LOW side of the high-voltage input cords is functionally
insulated from ground, there is no withstand voltage.
*: SELV (separated external low voltage): effective value of 30 V, peak
value of 42.4 V
1.2 Features
(1) Direct connection to the 3153
The 3930 can be directly connected to the 3153 AUTOMATIC
INSULATION/WITHSTANDING HiTESTER. Because the 3153 supplies
power to the 3930, no separate power supply is needed.
(2) Single mode and Multi-mode
The 3930 has two operation modes: single mode and multi-mode. Single
mode permits testing of eight channels using the one COM channel and
eight high-output channels. Multi-mode permits testing of four pairs of two
different high-output channels.
(3) Multiple channels
In single mode, the 3930 can test eight channels. In multi-mode, the 3930
can test four channel pairs. In addition, a unique ID can be set for each unit,
allowing a maximum of four 3930s to be connected to a single master unit.
(4) Output channel indicators
The LEDs on the front panel indicate the current mode and the channels that
are being output.
(5) Insulated design
The power supply, the high-voltage inputs and outputs, and the control input
connector signal wires are all functionally insulated.
(6) Signal level from 5 to 24 V
Devices ranging from general logic to a sequencer can be connected by
selecting the supply voltage for the control signal system.
(7) Safe design that avoids duplicate IDs
When multiple 3930s are connected, the unit can detect incorrect (duplicate)
ID settings. When a mistake is detected, all output is shut off.

If a 9615-01 or 9615-02 H.V.TEST LEAD will be in contact with or in the
vicinity of a metal surface while it is used, or if it must be used in a bundled
state, take measures such as wrapping the lead wire with a spiral tube that
will maintain a separation of 5 to 10 mm between lead wires or between the
lead wire and the metal surface. This will prevent capacitive coupling
between the lead wire and the metal surface or between lead wires, an
increase of leak current, or the radiation of noise.

2.1 Terms
______________________________________________________________________________________________
Chapter 2
Testing Arrangements
2.1 Terms
This section explains several terms that should be understood before using
this device.
(1) Master unit
The 3930 is a passive auxiliary tester that is connected to and controlled by
a master unit (the 3153 AUTOMATIC INSULATION/WITHSTANDING
HiTESTER, or a sequencer). The 3930 cannot operate on a standalone
basis.
In this manual, the term "master unit" is applied to devices that control the
3930 (such as the 3153 AUTOMATIC INSULATION/WITHSTANDING
HiTESTER or a sequencer) and to devices that supply high voltage or high
current and high voltage.
(2) IDs and distance from the master unit
Up to four 3930s can be connected to and independently controlled by one
master unit. In order to permit this, the unit has four scanner control signals
(inputs), and an ID can be set in order to select which scanner control signal
to use. The ID is represented by a number from "1" to "4," and is set by
means of the ID setting dial.
When connecting multiple units, only one unit can be connected directly to
the master unit; the other three are connected in daisy chain fashion to the
first 3930. In this manual, references to the distance between a specific
3930 and the master unit are based on the number of 3930s between the unit
and the master unit, not the physical distance of the unit to the master unit
or the relative value of the unit's ID number.

_____________________________________________________________________________________________
2.1 Terms
______________________________________________________________________________________________
WARNING
In order to avoid electric shock, a short circuit or damage to the
equipment, do not change the ID while the power is on for the 3930 or
the master unit, or while voltage is being applied.
NOTE When multiple 3930s are connected, note that when duplicate IDs exist, no ID error
is detected in the 3930 that is connected in the position that is farthest from the
master unit.
WARNING
In order to avoid electric shock, a short circuit or damage to the
equipment, do not change the ID while the power is on for the 3930 or
the master unit, or while voltage is being applied.
NOTE When multiple 3930s are connected to one 3153, set all 3930s to the same mode.
If 3930s set to different modes are connected to one 3153, a connection error will
be
g
enerated.
(3) ID error
This unit cannot be controlled correctly if the scanner control signal number
and the ID number do not match. In addition, in order to ensure safety, if
there is more than one 3930 with the same ID number connected to a single
master unit, an ID error is indicated on the 3930 with the duplicate ID
number. The ID error indicator LED lights, all output relays turn off in the
3930 with the duplicate ID, and that unit can not be controlled by the master
unit.
In this event, stop testing, turn off the power for the master unit and the
main unit, and set the IDs correctly.
(4) Single mode
In this mode, the 3930 tests eight high-voltage output channels paired with
the COM channel.
The devices being tested are connected between the high voltage output
terminal for each channel and the COM terminal. When this mode is set,
the mode indicator LED lights red, indicating single mode. All terminals for
CH1 to 8 on the 3930 are high-voltage output terminals. The voltage that is
input through the high-voltage input cord is output from the channels for
which the corresponding relays are on, and the output indicator LED lights
red.

_____________________________________________________________________________________________
2.1 Terms
______________________________________________________________________________________________
WARNING
In order to avoid electric shock, a short circuit or damage to the
equipment, do not change the ID while the power is on for the 3930 or
the master unit, or while voltage is being applied.
NOTE When multiple 3930s are connected to one 3153, set all 3930s to the same mode.
If 3930s set to different modes are connected to one 3153, a connection error will
be
g
enerated.
NOTE If a mode error is detected, the output relay is controlled but the voltage that is
input from the high-voltage input cord is not output on the high-voltage output pin.
(5) Multi-mode
In this mode, the 3930 tests four pairs of two different high-voltage output
channels. CH1 to 4 are connected to the high-voltage output (HIGH side),
and CH5 to 8 are connected to COM (LOW side). The device being tested
is connected between the two corresponding channels. If this mode is set,
the mode indicator LED lights green, indicating multi-mode. When the 3930
is connected to the 3153, it is possible to measure between multiple pairs of
different points by combining any one of CH1 to 4 and any one of CH5 to
8. The LEDs for the two channels that are being measured light, indicating
that measurement is occurring between those channels. The LEDs for the
high-voltage outputs (CH1 to 4) light red, and the LEDs for the COM
terminal (CH5 to 8) light green.
(6) Mode error
When MD1 of the status information (refer to chapter 3, "Control Signals
and Control Methods") is low, it indicates the existence of an abnormality in
an internal circuit, such as a slide switch, which means that the mode is not
set correctly.
When a mode error is detected, stop using the unit and contact your nearest
dealer or our sales office.
