Basler BE1-40Q demagnetization relay setting test

Test each TAP and HI gear in sequence, and record all points.

6.2 Delay characteristic verification

Using the same wiring, set TAP to A and delay to 11 (1.1s), 55 (5.5s), and 99 (9.9s), respectively.

The current jumps from zero to twice the operating current of the TAP gear (refer to Table 5-2 in the manual).

Measure the time from current application to output contact displacement with a timer, which should match the set value with an error within ± 5% or ± 50ms (whichever is greater).

6.3 Verification of Action Characteristic Curve (optional)

For situations where the entire 8 ° diagonal line needs to be verified, the operating current can be measured at different current phase angles (simulating different power factors), the corresponding P and Q can be calculated, and plotted on the complex power plane to verify whether it matches the theoretical 8 ° straight line. This method is suitable for laboratory calibration or fault analysis.

6.4 Output Circuit and Target Verification

Use the "Output Test" button to manually excite the output relay, observe whether the main and auxiliary contacts have shifted, and whether the target indicator is lit (if it is a current type, ensure that the tripping circuit has a current of at least 200mA).

Test power status output: Disconnect the control power supply, confirm that the status contacts are closed (normally closed), and open the contacts after restoring the power supply.

7. Maintenance and Storage Suggestions

BE1-40Q is a solid-state relay with simple daily maintenance, requiring only regular (recommended annual) functional testing. If stored for a long time as a spare part, it should be powered on for 30 minutes every year to maintain the performance of the internal aluminum electrolytic capacitor and extend its service life. If a malfunction occurs, do not disassemble or repair it on site. Instead, contact the manufacturer's technical support.
