2, the instructions
A connection
B function is introduced
Measure: | Dc voltage signal input directly, can monitor in real time measurement. |
Show: | 3 1/2 a digital display, can choose according to real-time measurement value by pressing the button, under-voltage alarm value. |
Control system: | Through the relay contact output control functions. |
Set the: | Through the monitor panel button, can be set two kinds of working state: display (real-time measurement), Set the under-voltage alarm Settings (voltage), the value of the adjustment to adjust potentiometer can be directly. |
C dc voltage measurement
Press the "set/show" button.Bounce, in display (real-time measurement) state, the dc voltage is to measure dc voltage value of the monitor display.
D setting under voltage value
Press the "set/show" button, under pressure, in the setting state, at this point is set the function state of dc voltage monitor, under-voltage by panel
Potentiometer to adjust the set value, the dc voltage is set under voltage value of the monitor display.After completion, under voltage value will display button to switch back to the state.
Four, installation,
1, site installation
A when installation, please according to the site environment, where possible, ensure the monitor display board face toward the observer;
B electrical cables with 12 ~ 14 shielded conductor;
C, please do not open the instrument shell, lest cause damage.
2, installation environment
Monitors should be installed in a dry, well ventilated place and away from heat source;
B environmental temperature for: - 10 ℃ to 50 ℃;
C working power supply: DC 15 V ~ 45 V
3, installation
Can use two kinds of DIN rail and screw installation, guide rail width of 35 mm, the screw size for M4 x 12.
