1. Place the loop driver in a suitable location. There are three placement options for
the PLS-X series drivers:
● In a 19" rack
● Hung on a vertical surface using the keyholes in the base of the unit
● On a flat level surface on the units rubber feet
Note
No ventilation space in the rack is required. When placed on flat surfaces the little space given
by the rubber feet is sufficient.
2. Connect the loop cable to the loop driver
using the Loop Terminals (11) as shown in figure.
3. Connect the power supply, first to the loop
driver’s DC Supply Jack (12) and then to the
wall outlet. The Blue ‘power On’ LED (10)
will illuminate.
4. Turn System Diagnostics (5) on by sliding the switch to the right. The Input Level
LEDs (2) will begin to blink.
5. Adjust the loop current. Depending on the adjusted current level, 1, 2, 3 or 4 out
put current LEDs will blink in unison.
6. Set the current to achieve a field strength of the peaks to approximately -3 dB in
the center of the loop.
The system is functioning correctly and is ready for commissioning in accordance
with the IEC performance standard IEC 60118-4.
7. Turn System Diagnostics (5) off, by sliding the switch to the left.
