_____________________________________________________________________________________________ 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.
(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.
Lights red if a duplicate ID is detected when multiple 3930s are ID error indicator LED connected. Sets the ID of this 3930. ID setting dial Sets the mode of this 3930 (single mode or multi-mode). Mode setting switch Turns on the 3930. POWER switch GlobalTestSupply www.
This cord is used to input high voltage. Use voltage to High-voltage input cord ground that is at or less than the SELV* on the LOW side. This connector is used to control the 3930. Control input connector This connector is used to connect multiple 3930s.
High side voltage output plug measurement on the 3930. Low side voltage Connect to the COM terminal on the 3930. output plug When used in a humid environment, it is possible that the H.V.TEST LEAD could NOTE attract moisture, creating an increase in leak current. Under these conditions, we recommend applying a moisture-proof spray to the 9615-01 or 9615-02, except for the metallic connector surfaces.
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.

2.3.3 Setting the ID In order to avoid electric shock or damage to the equipment, do not change the ID while the power is on for the 3930 or the master unit, or WARNING while voltage is being applied to the high-voltage input cord.
3930 or the master unit, or while voltage is being applied to the high-voltage input cord. 1. Confirm that the power is off for the master unit and for the 3930. 2. Connect the 3930's control input connector to the master unit.
1. Confirm that the high-voltage output from the master unit is off. 2. Connect the high-voltage input cord to the high-voltage output terminal on the master unit. 3. Using the H.V. TEST LEAD provided, connect the 3930 to the test portion of the device to be tested. High-voltage output terminal...
Carefully read Chapter 3, "Control Signals and Control Methods," check the supply voltage and the connections, and then turn on the power. Turn on the master unit first, before turning on the 3930. Turning on the power After first confirming that the master unit has already been turned on and that no voltage is being applied to the high-voltage input cord, turn the POWER switch ON ( ).
Do NOT connect the high-voltage input cord. 4. Set the 3930 to single mode, and then turn on the master unit and the 3930. After confirming that the mode indicator LED is red, confirm that there is no continuity between the HIGH and LOW sides of the high- voltage input cord.
