ZUBR VА-1 Digital Voltammeter

Installation and operation manual

Purpose

Before the installation and operation of the device, please read by the end of this document. This will help to avoid possible danger, mistakes and misunderstandings. Digital voltammeter VA-1 is designed for measurement and control in a single-phase circuit of:

• voltage;
• current;
• power (active, reactive or full);
• cos φ (allows you to estimate the power coefficient in your electrical grid).

The log for 100 cells allows you to keep statistics and save the maximum / minimum effective voltage and maximum current in the non-volatile memory.

Connection scheme

Supply voltage (100 – 420 V, 50 Hz) served on terminals 1 and 2, while phase (L) is determined by the indicator and activated on terminal 2 and neutral (N) — terminal 1. Load connecting wires are connected to terminals 3 and 4 (phase (L) is connected to terminal location 4, and zero (N) is connected to terminal location 3). Terminals 1 and 3 are structurally interconnected. Therefore, it is not necessary for zero to pass through the terminals.

The simplified internal circuit and connection scheme

Installation

The appliance is intended for installation inside residences. The risk of moisture or humidity in the installation site should be minimal. When installing in the bathroom, toilet, kitchen, pool appliance must be located in a shell with protection degree not below Ip55 per GOST 14254 (partial protection from dust and waterproof in any direction). The ambient temperature during installation should be within –5…+45 °С. The appliance is installed in a special box, which allows to conduct the easy installation and operation. Cabinet should be equipped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of two standard module on 18 mm. The height of the appliance should be in the range 0,5…1,7 m from the floor. For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit-breaker (CB). The automatic switch off is established in the open-phase fault wire, as shown at the scheme 2 and 3. It shall be calculated upon the rated load current.

To connect your device:

• fix the appliance on the mounting rail (DIN);
• take a wire;
• make the connection according to the passport.

Terminals of the device designed for wire cross section up to 16 mm2. To reduce mechanical load on the terminals it is desirable to use soft wire. Clean the end wires of 10±0,5 mm. If end is longer, it can cause a short circuit, and if short — cause unreliable connection. Use the cable lugs. Undo the screws of the terminals and insert tipped end of the wire in terminal. Tighten terminal with derived average 2,4 Н·m. Low tight may lead to low contact and overheating terminals and wires and over tight — damage terminals and wires. Wires protracted in terminals with a screwdriver with a shank width not more than 6 mm. Screw with shank width more than 6 mm may apply mechanical damage to terminals. This could result in loss of warranty.

Exploitation

Enabling

When turned on, the voltammeter displays the symbols of the displayed parameters for 2 sec, then measures and displays the values of the mains voltage and load current. If the voltage or current goes beyond the set limits, the corresponding screen will flash 1 time per second as an overrun type.

• the upper limit is exceeded,
• the lower limit is exceeded,
• current limit exceeded.

Blinking of the green LED 1 time per 2 sec indicates the appearance of a new, not viewed record in the log.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM

At turning on neither indicator nor led do not shine.

• Possible cause: There is no power supply voltage on terminals 1 and 2.
• It is necessary to: Ensure supply voltage presence.
• If you have any questions call the Service centre the telephone number listed below.

Safety instructions
