Safety Precautions

WARNING

The Sentry Plus Series Hipot Tester can provide an output voltage as high as 6000V DC (5000V

AC) to the external device under test (DUT). Although the Sentry Plus unit is designed with full

attention to operator safety, serious hazards could occur if the instrument is used improperly and

these safety instructions are not followed.

1. The Sentry Plus unit is designed for operation with its chassis connected to earth ground. The instrument is shipped with a three-prong power cord to provide this connection to ground. This power cord should only be plugged in to a receptacle that provides earth ground. Serious injury can result if the Sentry Plus is not connected to earth ground.

2. Tightly connect cable(s) to the (blue) RTN/LOW terminal. If this is not done, the DUT’s casing can be charged to the high voltage t est level and serious injur y or electri cal shock hazards could result if the DUT is touched.

3. Never touch the metal of the High Volta ge probe directl y. Touch only the insulated parts of the lead(s).

4. Never touch the test leads, test fixture or DUT in any manner (this includes insulation on all wires and clips) when the high voltage is applied and the red DANGER light is ON.

5. Before turning on the Sentry Plus unit, make sure there is no device (DUT) or fixture connected to the test leads.

6. After each test, press the [STOP] (red) button for safety if there is an y concern that HV may still be applied to the output terminals.

7. When the red DANGER LED is lit or flashing, NEVER touch the device under test, the lead wires or the output terminals.

8. Before touching the test lead wires or output terminals make sure:

a) The red [STOP] button has been pressed b) The red DANGER LED is OFF.

9. In the case of an emergency, turn OFF the POWER switch using a “hot stick” and disconnect the AC power cord from the wall. DO NOT TOUCH THE Sentry Plus INSTRUMENT.

10. If the DANGER LED does not go off when the [STOP] button is pressed, immediately stop using the tester. It is possible that the output voltage is still being delivered regardless of the TEST ON/OFF control signal.

11. When the Sentry Plus instrument is used in remote control mode, be extremel y careful. The High Voltage Output is being turned on and off with an external signal.

Condensed Operating Instructions

WARNING

High Voltage is applied to the white HV Output Terminal anytime the red DANGER LED is ON

or flashing. Always make sure the DANGER LED i s OFF when connecting or disconnecting

the device under test (DUT).

General Information

The Sentry Plus Series Hipot Tester is a measuring instrument for direct readout of hipot output voltage and leakage current and insulation resistance. The voltage applied to the device under test is adjustable from 50V to 5kV AC and 50V to 6kV DC. The trip current limit is programmable from 1uA to 20mA AC in 1uA steps and from 0.1uA to 5mA DC in 0.1uA steps. The output voltage for Insulation Resistance tests is 50V to 1000V DC over a measurement range of 100kΩ to 50GΩ.

Start-Up

The Sentry Plus Series unit can be operated from a power source betw een 90 and 250VAC at a power line frequency of 50 or 60Hz. The standard Sentry Plus Series unit is shipped from QuadTech with a 3.15A fuse in place for AC 90 -130V operation. (A 1.6A fuse is included for 200-250V operation). The Sentry Plus unit is shipped with the line voltage selector set for 120V. Refer to paragraph 1.4.3 for instructions on changing the fuse or line voltage selector.

Connect the Sentry Plus Series unit AC power cord to the source of p roper voltage. Operate the Sentry Plus Series instrument with its chassis connected to earth ground. The Sentry Plus instrument is shipped with a three-prong power cord to provide this connection to ground. This power cord should only be plugged into a receptacle that provides earth ground. Serious injur y may result if the Sentry Plus Series instrument is not connected to earth ground.

Press the [POWER] button on the front panel to apply power. To switch the powe r off, press the [POWER] button again or if measurements are to be made proceed with the Test Parameter Setup in Table COI-1. The Sentry Plus Series instrument should warm up for 15 minutes prior to use.

UL Requirements

The Sentry Plus Series instruments meet the requirements outlined by U L for Hipot Testers. The Sentry Plus indicates the test potential (test voltage), has both visual and audible indication of failure and the STOP switch must be manually pressed prior to another measurement being made. The Sentry Plus Series instrument has a 100VA output [(5000V * 20mA) = 100VA]. The Sentry Plus Series instrument also measures and displays the output voltage directly at the output terminals during the test.

1.4.2 Instrument Positioning

The Sentry Plus unit contains a graphic display for direct readout of measured parameters. The optimum angle for viewing is slightly down and about 10 degrees either side of center. For bench operation the front flip feet should always be used to angle the instrument up. In bench or rack mount applications the instrument should be positioned with consideration for ample air flow around the rear panel fan ventilation hole. An open space of at least 3 inches (75mm) is recommended behind the rear panel. Testing should be performed on a non-conductive surface. An ESD mat is not a recommended test platform.

1.4.3 Power Requirements

The Sentry Plus instrument can be operated from a power source of 90 to 132V AC or 198 to 250V AC. Power connection is via the rear panel through a standard receptacle. Before connecting the 3-wire power cord between the unit and AC power sour ce, make sure the voltage selection switches on the rear panel (Fi gure 1-5) are in accordance with the power sour ce being used. For a 90-132V source, use a 3.15A 250V fuse. For a 198-250V so urce, use a 1.6A 250V fuse. Always use an outlet that has a properly connected protection ground.

WARNING

MAKE SURE THE UNIT HAS BEEN DISCONNECTED FROM ITS AC POWER SOURCE

FOR AT LEAST FIVE MINUTES BEFORE PROCEEDING.

Procedure For Changing A Sentry Plus Series Fuse

Remove the fuse drawer, by pressing the black tab located at the center of the extended fuse drawer, just below the 3-prong receptacle, and pull outward.

Once the fuse drawer has been removed from the instrument slide out the fuse from the holder and replace. Make sure the new fuse is of the proper rating. Note that the fuse drawer can also be used to store a spare fuse.

Install the fuse drawer back in the inlet module by pushing in until it locks securely in place.

1.4.4 Safety Inspection

Before operating the instrument inspect the power inlet module on the rear of the Sentry Plus to ensure that the properly rated fuse i s in place, otherwise damage to the unit is possible. M ake sure that the voltage selector swit ches are set in accordance with the power source in use. R efer to paragraph 1.4.3 and Figure 1-5.

The Sentry Plus instrument is shipped with a standard U.S. power cord, QuadTech P/N 42000300 (with Belden SPH-386 socket or equivalent, and a 3-wire plug conforming to IEC 320). Make sure the instrument is only used with these cables (or other approved international cord set) to ensure that the instrument is provided with connection to protective earth ground.

The surrounding environment should be free from excessive dust to prevent contamination of electronic circuits. The surrounding environment should also be free from excessive vibration. Do not expose the Sentry Plus instrument to direct sunlight, extreme temperature or humidity variations, or corrosive chemicals.
