5 Electrical installation
The interface to the copy sensor is a 7-pin connector with the following pin-out:
Matching connector: Amphenol Tuchel T3476 001, delivered with the sensor.
Pin 1 :
+24VDC power
Pin 2 : + Output (collector)
Pin 3 : + Speed Sensor Input
Pin 4 : - Speed Sensor Input
Pin 5 : - Output (emitter)
Pin 6 : 0V
Pin 7 : No function (connected to pin 6 internally)
5.1 Power Connection
Proper wiring techniques are essential for successful system installation. To reduce the
effects of electrical noise interference and static discharge, the procedures outlined in this
section must be strictly followed.
The sensor shall be connected to 19 - 30V DC regulated power.
It must be free from transients!
Never connect or disconnect any cables when the power is on!
The normal current consumption is around 200mA
5.2 Output Signal
The output is a normally open, opto-isolated transistor. Every output pulse is signaled as a
closing of the output for a certain time; see also “DIP-Switch Settings” in chapter 5.
The spec for the output opto coupler is as follows:
Max load current: 150mA, Max voltage: 35V DC
5.2.1 Output Signal - Connections
The output can be used for both "current source" and "current sink" depending on what is
required for the following equipment. In current source mode, the sensor output will give a
positive pulse to the stacker/totalizer when active. In current sink mode, the sensor output
will give a negative pulse. Figures 5.2.1.1 and 5.2.1.2 shows a common 24V as power
supply and as the supply for the pulse. It is of course possible to have different power
supplies. In that case, the 24V-power is connected to pins 1 and 6, and the totalizer is
connected to pins 2 and 5.
