The Trotec BE20 is a bipolar voltage detector designed for indicating voltage ranges in electrical installations. It is suitable for use in facilities of overvoltage category 3 (CAT III = domestic installations). The device automatically detects voltage ranges between 12 and 690 V DC or 12 and 400 V AC.

Function Description:

The primary function of the BE20 is to indicate the presence and range of voltage. It features an 8-section LED display that shows voltage amounts and their polarity. The device can perform unipolar phase testing, continuity testing, and rotary field direction display. For unipolar phase testing and rotary field direction display, the device requires charged batteries. The BE20 is also equipped with an integrated LED torch to facilitate voltage detection in poorly lit areas.

Important Technical Specifications:

• Voltage Indication: 12/24/36/50/120/230/400/690 V AC/DC, automatically detected.

• Battery: 2 x 1.5 V AAA.
• Weight: 237 g.

Unipolar Phase Testing:

• Voltage Range: 100 to 690 V AC.
• Frequency Range: 50/60 Hz.

Continuity Test:

• Measuring Range: < 300 K Ω.
• Test Current: < 5 μA.
• Overvoltage Protection: 690 V AC/DC.

Phase Sequence Indicator:

• Voltage Range: 100 to 400 V.
• Frequency Range: 50/60 Hz.
• Measuring Principle: Double-pole and contact-electrode.

Usage Features:

• Safety First: Users must be qualified electricians familiar with safety rules (de-energise, secure against restart, verify de-energised state, earth and short-circuit, cover neighbouring live parts). The device should always be tested for proper functioning on a known voltage source before each measurement.
• Bipolar Voltage Detection: The device operates without battery supply for bipolar voltage detection.
• Battery Requirement: For unipolar phase testing, continuity testing, rotary field direction display, and the LED torch, two 1.5 V AAA microbatteries must be inserted.
• Autotest Function: The device includes an autotest button (5) to check its functionality. Pressing and holding this button for a few seconds should illuminate the continuity test indication (12), all voltage detection LED displays (14), and emit an acoustic signal if the test is successful.
• Voltage Indication: When both test probes (1, 2) touch measuring points of a voltage source, the respective voltage detection LED displays (14) and polarity indicator (13) illuminate. If both AC+ and AC- indicators illuminate simultaneously, an AC voltage is present.
• Unipolar Phase Testing: To perform unipolar phase testing, touch the measuring point with test probe L2 (2). The unipolar voltage detection phase display (9) will illuminate, and an acoustic signal will be emitted if an AC voltage exceeding 100 V is detected.
• Continuity Test: Ensure the electric circuit is switched off and all capacitors are discharged. Touch the de-energised measuring object with both test probes (1, 2). A successful continuity test is indicated by an acoustic signal and the illumination of the continuity test indication (12).
• Rotary Field Direction Display: Touch the voltage source with both test probes (1, 2). The left-turning (L) or right-turning (R) rotary field direction display (11) will illuminate based on the measurement result.
• LED Torch: Press and hold the LED torch power button (6) to illuminate the LED torch (3) for easier visibility in dark environments. Releasing the button switches off the torch.
• Test Probe Protectors: After each use, screw the supplied test probe protectors onto the two test probes to prevent injuries.
• Limitations: The device cannot display DC voltages within the range of approximately 0 V to 8 V. The actual voltage can be up to 30% lower than the indicated value due to display tolerance.

Maintenance Features:

• Battery Change: A battery change is required when the continuity test indication (12) no longer illuminates and no acoustic signal is emitted during the function test. To change batteries, loosen the screw below the battery compartment cover (7), remove the cover, insert two 1.5 V AAA batteries with correct polarity, replace the cover, and retighten the screw.
• Cleaning: Clean the device with a soft, damp, and lint-free cloth. Ensure no moisture enters the housing. Do not use sprays, solvents, alcohol-based cleaning agents, or abrasive cleaners.
• Repair: Do not modify the device or install any spare parts. For repairs or testing, contact the manufacturer.
• Storage: Store the device in dry conditions, protected from frost, heat, dust, and direct sunlight. Remove batteries if the device will not be used for an extended period.
• Disposal: The device, batteries, and accumulators must be disposed of professionally according to relevant legal requirements, not with household waste. Collection points for waste electrical and electronic equipment are available, and information can be obtained from local authorities or Trotec's website.
