| CPOL2 and CPOL3 are designed to check a series of test points for correct polarity and wiring errors. The checks can be performed on current and voltage transformers, and on the connected wirings and terminals. In addition, CPOL3 can display the voltage and, if combined with a current clamp, the current of the measured signal (→ C-Probe 1 and Chauvin Arnoux E25). Functional principle: Use COMPANO 100 to generate a DC-free, sawtooth-shaped signal (voltage or current), which is detected by the polarity checker. Check the polarity at all terminals of your choice. Following this procedure provides a clear indication as to whether the polarity is OK (green happy face LED) or not OK (red sad face LED). For more details and safety instructions refer to the corresponding user documentation. |

C-Shunt is a precision shunt for current measurements. Insert it directly into COMPANO 100's BINARY/ANALOG inputs IN 1 or IN 2 to make the input a current input.
There are two variants available: C-Shunt 1 and C-Shunt 10.
| C-Shunt 1 | C-Shunt 10 | |
| Electrical resistance | 0.001 Ω | 0.01 Ω |
| Resistance tolerance | 0.1 % | 0.1 % |
| Temperature coefficient | ≤ 30 ppm/K in the range of 0 ... 70 °C (+32 ... 158 °F) | ≤ 15 ppm/K in the range of 0 ... 70 °C (+32 ... +158 °F) |
| Maximum current | 32 A continuous | 12.5 A continuous |
| Item number | B0620201 | B0620301 |
When connecting the shunt, note the maximum current ratings imprinted on the shunt.
Configure the input IN 1 or IN 2 to be a current input using a shunt by pressing the respective input key and by stepping through the configuration order (see Configuring IN 1/IN 2 (binary or analog inputs)).

| The BNO1 is a solid-state relay, designed for direct connection to the V OUT voltage output of COMPANO 100. By outputting a DC voltage of 20 to 300 V DC, the BNO1 will close its output. This function can be used to trip a circuit breaker or to trigger a logic function. For more details read the BNO1 User Manual. That manual also contains important safety instructions. |
|
| The VBO4 is a voltage transformer accessory for COMPANO 100. It transforms the COMPANO 100 device's output voltages of 0 ... 150 V to 0 ... 300 V or 0 … 750 V. This enables you to test over-voltage or frequency relays with COMPANO 100 which require a voltage higher than 150 V. Furthermore, it can be used to test voltage sensors or voltage transformers with voltages of over 150 V. You can also test renewable energy systems such as wind power, biogas, photovoltaic, small hydroelectric power, and combined heat and power plants. Furthermore, you can test industrial networks with voltage levels of over 150 V. For more details read the VBO4 User Manual. That manual also contains important safety instructions. |

| The CBF1 is a 10:1 current transformer for COMPANO 100, used to reduce distortions while testing self-supplied relays. The CBF1 input is directly connected to the high-current output of COMPANO 100. The CBF1 output is then connected to the current input of the self-supplied relay under test. The CBF1 transforms the COMPANO 100 output current of up to 110 A into a smaller test current of up to 11 A. For more details read the CBF1 User Manual. That manual also contains important safety instructions. |
The handheld grounding tester HGT1 measures step and touch voltages. Using the COMPANO 100 test set, test currents at variable frequencies can be safely fed into a distant current probe to simulate a ground fault. According to EN 50522 and IEEE 81 standards, HGT1 measures step and touch voltages at various locations at the same time. Digital filtering makes noise suppression more effective and measurements more accurate.

The SAA2 is a multifunctional safety accessory to increase safety awareness while working with dangerous voltages or currents. It consists of a control unit and one or more signal lamps which are fixed at or near the test object. Each signal lamp provides an emergency stop button to switch off all outputs of the main device immediately and to bring the test setup into a safe state. A green continuous or a red continuous/flashing light indicates the status of the main device.
Optionally, the signal lamps can generate an acoustic signal if an output of the main device is active.
The SAA2 is compatible with various OMICRON test systems, including COMPANO 100.
For more information refer to the supplementary sheet "Functions and Handling of Safety Accessories".
| The SAA3 3-position remote safety switch is an emergency switch for use with various OMICRON test systems, including COMPANO 100. The SAA3 triggers the emergency stop of the connected test system. |
|
The SAA3 has three operating positions shown below:
| Operating position | Action | Description |
|---|---|---|
| I | Do not press the switch. | Emergency stop is activated. |
| II | Press the switch into middle position. | No activation of emergency stop. |
| III | Press the switch all the way. | Emergency stop is activated. |
For more information refer to the supplementary sheet "Functions and Handling of Safety Accessories".
