Frequently Asked Questions - KS3 Sanwa

How do I check the phase sequence of a three-phase line using the KS3?

Connect the measurement clips to R-S-T (red to R, white to S, blue to T). Turn on the power. Ensure all open phase indicators are lit. The CW (green) indicator lights for positive phase (clockwise), and the CCW (red) indicator lights for negative phase (counterclockwise).

How do I test the rotation direction of a motor before connecting power?

Connect the clips to motor terminals L1-L2-L3. Turn the motor shaft manually at a speed higher than 2 rotations per second. The CW indicator lights green for clockwise rotation, and the CCW indicator lights red for counterclockwise rotation.

What does an open phase indicator mean?

Each of the three open phase indicators corresponds to a line (R, S, T). If an indicator is OFF, that phase is open (disconnected or no voltage). The indicator lights at inputs above approx. 30 V.

How do I replace the battery in the KS3?

First, disconnect the measurement clips from any source and turn off the power. Remove the fixing screw on the battery compartment cover, slide the cover downward, replace the 9V battery with a new one, reattach the cover and tighten the screw.

What safety precautions should I take when using the KS3?

Never use on circuits exceeding 500 V. Avoid using if the instrument or clips are damaged. Do not remove the battery cover during use. Pay special attention when measuring voltages above AC 33 Vrms or DC 70 V. Always follow the WARNING and CAUTION instructions in the manual.

Can I use the KS3 on single-phase lines?

No, the KS3 is designed for three-phase systems only. It cannot be used with three single-phase lines.

What is the warranty period for the Sanwa KS3?

The KS3 is warranted against defects in workmanship or material for 1 year from the date of purchase, valid only in the country of purchase from an authorized Sanwa agent or distributor.

How do I clean and store the KS3?

Clean with a dry cloth; do not use solvents like thinner or alcohol. Store in a cool, dry place away from direct sunlight and heat sources. Remove the battery if not used for an extended period.

What should I do if the power ON indicator does not light?

First, check the battery. If the battery is depleted (voltage below approx. 6.0 V), replace it with a new 9V battery. If the indicator still does not light, the instrument may need repair; contact an authorized Sanwa service center.

Can the KS3 detect open phases on a motor that is not powered?

No, the open phase indicators require a voltage above approx. 30 V to light. During motor rotation testing (without power), these indicators will not light. The CW/CCW indicators may still respond, but open phase detection is not possible without applied voltage.

2-1 Application

This instrument is a motor rotation faster & 3-phase detector that allows you to determine the rotation direction of a three-phase motor by turning the motor shaft manually; as well as to check the phase sequence (positive, negative) and open phase condition of three-phase lines.

2-2 Features

- Safety design that complies with IEC61010-1 CAT. III 500 V

• Motor rotation direction testable before connection of the power supply.

- Phase sequence and open phase checking of three-phase lines - Bright LED indicator

Mamata on the back

- Magnets on the stock of the main unit show it to be fixed on its distribution board and other metallic objects.

[3] NAMES OF PARTS

[4] DESCRIPTION OF FUNCTIONS

4-1 Power switch

Switches the power on and off. After measurement, be sure to set this switch to OFF to prevent wasteful battery consumption.

Note. This instrument does not have the auto power-off

4-2 Open phase indicators

In the three-phase power line check, each indicator lights up when the corresponding line is live. An extinguished indicator means that the phase of the line is open.

Note: Each LED indicator lights at an input of about 30 V or more. These indicators do not light during the motor rotation check because the input voltages are less than 30 V.

4-3 Input jacks

Insert the measurement cords into the jacks of the same colors.

4-4 CW indicator (Clockwise = positive phase)

Lights (in green) when the phase is positive.

4-5 CCW Indicator (Counterclockwise = negative phase)

Lights (in red) when the phase is negative. 4-8 Power ON indicator (Low battery warning)

1. Power on indicator (Low, Butler) Warning. Lights when the power is on

It stops lighting when voltage of the built-in battery drops to 6.0 V or lose. Replace the battery with a new one as soon as possible if the indicator will not light.

[5] MEASUREMENT PROCEDURES

WARNING

1. Do not perform measurement of a voltage exceeding the maximum rated voltage.
2. During measurement, do not hold the measurement clip at any point beyond the barrier.

5-1 Pre-operational Check

Perform pre-operational check for safety.

- Check the external appearance. Check that there is no abnormality with the main unit and measurement clips. Check that there is no abnormality with the cord such as disconnection or cracking.

- Check the lighting of the open phase indicators and the functioning of the phase detection by clipping cables with known voltages and phases. If one or more indicator(s) do not light, the measurement cord(s) may be disconnected or the built-in fuse may be blown.

Note: For the fuse replacement, please contact us (see section 7-2).

- If the Power ON indicator will not light, replace the battery with a new one.

5-2 Checking the three-phase power lines

CAUTION

1. The open phase indicators do not light if any of the line voltages is less than 30 V.

2. The CW or CCW indicator lights up even when there is an open phase, but the operation is not guaranteed. Be above sure to check the phase

but this operation is not guaranteed. Do always sure to check the phase sequence while all of the open phase indicators are ON.

1. This instrument cannot be used with three single-phase lines.

(1) Insert the three measurement cords into the input jacks.

(2) Set the Power switch to ON.

(3) Connect the three measurement clips to R-S-T of the three-phase AC power supply as shown below (correct measurement is impossible if only two of them are connected).

Connect the red measurement clip to R, the white measurement clip to S and the blue measurement clip to T

Note: Illustrations of ON/OFF status of the indicators in this manual

(4) Check the open phase.

In the example above, the indicators of the R- and S-phases are ON and the indicator of the T-phase is OFF, which means that the phase of T is an open phase. * The CW or CCW indicator lights up even when there is an open phase, but the operation is not guaranteed. Be always sure to check the phase sequence while all of the open phase indicators are ON

(5) Check whether the phase is positive or

negative.

5-3 Checking the motor rotation direction

A CAUTION

1. Before measurement, make sure that no voltage is applied to the motor.
2. If an open phase is detected in the motor rotation direction check, turning the motor shaft in either direction lights either or none at the CW and
   CCW indicators. Be sure to check by turning it in both directions.
3. Correct judgment is impossible if the turning speed is low. Be sure to
   check by turning the motor shaft at a certain speed (the specified rotation speed cannot be reached if it is half stopped or turned at a low speed).

(1) Insert the three measurement cords into the input jacks.

Set the Power switch to ON.

(3) Connect the three measurement clips to L1-L2-L3 of the motor as show below (correct measurement is impossible if only two of them are connected).

(4) Turn the motor shell at a speed higher than the specified rotation speed.
When the phase is positive (clockwise), the CW indicator lights green. When
the phase is negative (counterclockwise), the CCW indicator lights red.
The specified solution spots refers to 2 relations of more per sols. This figure is variable depending on the number of motor poles.
* If there is an open phase, turning the motor shell in silk
either or none of the CW and CCW indicators. Be sure to check by turning it
in both directions.
* Certain motors may rotate in the opposite direction when they are connected in
