1.2. Power supply and control signals.
note:
Power supply and control inputs have a common "ground" - without galvanic separation.
The inputs can be programmed (see p.5.3) as non-inverted without choke or negated with pull up to
+5V. In the second case, you can control the inputs of the indicator by means of passive contacts that
connect the appropriate inputs to the ground, which allows you to bypass the issue of different
operating voltages of the control circuit. It is also possible to control the inputs of the indicator
by means of open collector outputs..
2. Basic requirements and safety of use.
Meaning of symbols:
−it is particularly important to read before connecting the indicator. Failure to comply
with the remarks marked with this symbol may cause damage to the indicator or the
occurrence of hazards.
−means relevant parts of the description regarding the specific characteristics of the
indicator. In terms of operational safety, the indicator meets the requirements of the
PN-EN 61010-1 standard.
2.1. Security considerations:
.
−The installation and connection of the indicator should be carried out by qualified personnel,
−All available protection requirements should be taken into account,
−Before switching on the power supply, check the correctness of electrical
connections,
−Before disassembling the indicator from the board, it should be disconnected
from the power supply.
3. Installation
.
3.1. Mechanical fastening
The indicator is designed for mounting in a standard Ø22.5mm hole with a positioning cut-out at the
top. Mounting the indicator to the board boils down to inserting the body into the prepared hole and
screwing it from the rear with the fixing nut..
1.1. Electrical connections
The indicator is equipped with six screw terminals.
The maximum cross-section of wires - 0.5mm2.It is recommended to solder or use cable
ends with solder ends. The input signal (current or voltage) should be connected between
terminal In and ground (common with the ground).
The alarm outputs Al L and Al H are of the open NPN collector type.
Output transistors: Umax = 100V Imax = 800mA.
Terminal designations and electrical connections are shown in Fig.2
