National Machinery Ministry. It is suitable for taking measurement and control of oil temperature in a medium-
sized or Large-sized Transformer.

Main Technical Parameters:
1, Normal operating conditions: (-30~+55)º C
2, Measuring range: 0~100 0~120 0~150
3, Indicative accuracy: 1.5 grade
4, Control function:
(1). Setting range: Adjustable within the whole span
(2). Setting accuracy: ± 3
(3). Switch difference: 6± 2
(4). Rated power of switch: AC 250V/3A
(5). Standard set Point:
0-100: K1=55 K2=65 K3=80 K4=90
0-120: K1=55 K2=65 K3=80 K4=100
0-150: K1=55 K2=65 K3=80 K4=130
5, Output:
(1). Pt 100 platinum resistance signal
(2). DC (4-20) mA signal
(3). DC (0-5) V signal
6. Protection grade: IP55

4, Control point setting
4.1 Of VBWY-804 Thermoregulator:
The temperature control points of eachV BWS- 804 have been already set in accordance with JB/T6302-92
standard before its delivery. (refer to: 3. Main techuical parameters) If users need to change the value of set
points, please follow below procedures:
4.1. 1 take off the meter cover with a supplied 10mm solid wrench;
4.1. 2 Unscrew switch fixed bolts with a supplied 6mm solid wrench (refer to figure 4 );
4.1. 3 stir the red setting needles to set value planned;
4.1. 4 screw back switch fixed bolts;
4.1.5 close the cover.
4.2 Of VXMT-288F/288FC digital display thermometer:
4.2. 1 shift the toggle switch to "set" position(Figure 3 );
4.2. 2 Adjust the regulating potentiometer until the temperature value planned;
4.2. 3 shift the toggle switch back to "measurement" position.
