INSTALLATION
3.5.3
Connecting the analog and digital outputs
In the non-ex zone, the analog output must be connected using an Ex separation stage with
a maximum sense resistance of 200 Ohm (e.g., SICK 6051123).
The digital output is implemented as a NAMUR contact. This must be connected in the Ex-
free zone using a NAMUR switching amplifier (e.g., SICK 6051124).
1
Ensure the voltage is switched off.
2
Remove the cover of the TSA151 voltage supply unit.
3
Push the cable through cable gland (2).
4
Connect analog output Analog out + and
−
.
5
Connect digital output Digital out + and
−
.
6
Connect the shielding to shielding terminal (4).
7
Close the cable gland. Tightening torque: 10 Nm.
8
Ensure the cable gland seals the cable.
9
Connect digital output D-out of the TSA151 voltage supply unit.
3.5.4
Connecting power supply to the TSA151 voltage supply unit
●
Supply voltage, as in the Technical Data,
1
Ensure the voltage is switched off.
2
Remove the cover of the TSA151 voltage supply unit.
3
Push the cable through cable gland (1).
4
Connect the supply voltage to ter24V and GND.
Terminal FE serves optional internal connection of the functional ground.
5
Close the cable gland. Tightening torque: 3 Nm.
6
Ensure the cable gland seals the cable.
Observe the specifications in the Technical Data,
.
CAUTION:
Electrical voltages!
▸
Always ensure the lines are disconnected before starting any electrical work.
A 24 PELV power supply unit is mandatory for the supply to guarantee an Um fault
voltage of 60 V.
SICK Part No. 6042607 or 6034520 (for use in zone 2).
The 24V PELV power supply unit must have an overvoltage protection device.
In order to switch the TSA151 disconnected from the mains and potential-free, a
disconnecting device must be planned in the non-ex zone before the PELV power supply
unit. Fit the disconnecting device as close as possible to the measuring device and
easily accessible.
