PCM_V2.1 12.2018
Introduction
The Power & Communications Module (PCM) contains the high
voltage power supply, digital and analog communication interfaces
for Lovibond®Process Sensors.
A qualified electrician trained in the installation of electrical
equipment should read and understand this manual prior to working
with this component as potential lethal hazards are present.
The manufacturer does not take responsibility for any issues caused
by use of the unit not in accordance with the instructions in this
manual.
Preface
Do not exceed temperatures or time spans in any case.
All warning labels must NOT be removed and should be replaced if
they become damaged or faded.
Important Information
The PCM can be mounted to a panel or to a wall.
Notes on power connection
The PCM should be permanently connected to mains power.
See local building codes for permanently connecting equipment.
Safety instructions for operation
Never open the high voltage housing while the PCM is connected to
mains power. There is a danger of electric shock and other hazards.
The high voltage area may only be opened and serviced by qualified
professionals.
Ensure proper grounding of the metal bonding plate near the bottom
of the enclosure. It must be connected to GND for proper operation.

High Voltage Installation
NOTICE
A local disconnect mounted in a suitable and easily reached location must be included
in the installation of this equipment. The local disconnect must be marked as the
disconnecting device for this equipment.
NOTICE
This unit was tested with metallic conduit as per UL 61010-1 with a bending moment of
34Nm (300 lb-in) at a horizontal distance of 300mm (12").
Do not exceed this bending moment.

3. Remove the appropriate hole plugs from the bonding plate.
The two near the back are intended for high voltage use.
Use proper connection hardware to ensure grounding connection to
metal bonding plate. (see Figure 5)
4. Connect AC power to the connector labeled J1 (see Figure 6 for
power connector location). AC power and protective earth wires
must be 12 to 18 AWG. A local disconnect switch or circuit breaker
which meets local electrical code is also required on the AC power
input, and must be located near the PCM.
5. Connect Relay outputs to connectors labeled J2, J3, and J4. Note that
Normally Open (NO) and Normally Closed (NC) contacts are provided.
See Figure 6 for wiring information.
6. Reinstall the low voltage board connectors at position J102 and J109
and the red thumb screw.

ELECTRIC SHOCK HAZARD. The barrier must stay in place except when a qualified
installation technician is connecting power or relay outputs.
CAUTION
ENSURE PROPER GROUNDING. Connect metal bonding plate to protective earth
for proper operation.
WARNING
POTENTIAL FIRE HAZARD. The relay contacts are not fused and are rated at 5A max.
External devices should have a current limiting device to keep the current below 5A.
