This manual covers ANZ 200 indicator (hereinafter referred to as "device"); it contains technical data,
description of design and other information necessary for proper application and maintenance of the device.
There are several versions of the device. Refer to specifications (www.piezus.ru), full code of the device, for
the version information.
Production regulated by TOR 4212-000-7722857693–2015.
Terms and abbreviations used in the manual: Span – measurement range; URL – upper range limit (a.k.a
URV).
1 Purpose of the device
1.1 The device converts unified current signal (4 ... 20 mA) into present value of the parameter controlled
and delivers it to the display; it is also capable of controlling an external electric circuit from the built-in
switch.
1.2 The device is a local indicator for any general purpose industrial transmitter that outputs a unified signal
of 4...20 mA (2 wire) through a DIN 43650 connector.
1.3 Applications: control, safety, signaling and supervision systems in various industrial environments and at
public utilities.
2 Technical specifications
2.1 General technical data
2.1.1 The device:
- displays current values of the parameter measured by the connected transmitter in a user-friendly form
(units of measurement selected by user);
- stores peak values registered and shows graphs covering last hour, day, month, quarter;
- activates switch output when the controlled parameter reaches a set threshold;
- accepts operating mode adjustments made with control buttons (on the front panel).
- prevents unauthorized access to settings with a password.
2.1.2 The device is mounted onto a transmitter with a DIN 43650 connector; it is powered by the
transmitter's current loop (resulting voltage is 6.5 V).
2.1.3 Resolution of the OLED display is 128 × 64 pixels; it measures 30 × 16 mm (see Table 1 for its basic
specifications).

* Accuracy includes non-linearity, hysteresis and repeatability (under IEC 60770).
2.1.5 Housing of the device is plastic (see Supplement A). The display rotates for 330° in one plane (relative
to the connector).
2.1.6 Housing dimensions, mm, max: 81 × 69 × 48 mm.
2.1.7 Weight, max: 0.11 kg.
2.1.8 Housing ingress protection (GOST 14254) - IP65.
2.2. Operating conditions:
- enclosed explosion-proof spaces free from aggressive vapors and gases;
- ambient air temperature from -25 to +85 °С, relative humidity from 5 to 95% (no moisture condensation);
- atmospheric pressure from 84 to 106.7 kPa (group P1 under GOST R 52931, max height above sea level -
1000 m).
Resistance to mechanical attack puts the device in group F3 under GOST R 52931: resistant to sinusoidal
vibration with acceleration of 49 m/s2, frequency (10 ... 500) Hz and amplitude of 0.35 mm.
2.3 Electromagnetic interference resistance and emission
Electromagnetic emission: the device is a Class A equipment under GOST R 51318.22.
Electromagnetic interference resistance: the device is a class 3 equipment under GOST R 51317.4.3.
3 Safety precautions
3.1 The electric shock hazard class of the device is III (no dangerous voltage); see GOST 12.2.007.0 for full
classification.
3.2 Take measures to prevent moisture from getting into the housing and onto connector pins.
4 Installation instructions
4.1 Install the device with maintenance convenience (incl. mounting, dismantling) in mind. Rotate the display
to position it for convenient reading.
4.2 Always cut off power when connecting the device's circuits.
4.3 Connect circuits through the connector as prescribed by Appendix B.
5 Setup
5.1 General information
5.1.1 There are control buttons and a display on the front panel of the device. Press any button to cycle
through displayed information (see Figures 1-4).
Figure 1 - Switchable screens displaying the measured value
Figure 2 - Switch screen showing current switch output parameters
Figure 3 - MIN/MAX screen showing minimal and maximal values for 1 hour (press a button to cycle through
other interval options: 24 hours, 30 days, 90 days)
Figure 4 - Graph screen showing the signal change graph (vertical axis adjusts automatically to fit into the
display)
Factory settings of the switch: mode - hysteresis; switching-on threshold - 55% of URL;
switching-off threshold - 45% of URL; switching-on delay - 0 s; switching-off delay - 0 s.
