Connection using Meech 24VDC power supply
Meech 24V DC supplies are grounded internally. It is important that the mains
connection offers a ground connection. Two-pin outlets without a ground connection
must not be used, unless the ground post on the 971IPS-15 bar is connected to
ground.
The switchmode power supply has a standard IEC C13 mains socket and a 2000mm
HT cable to M8 Connector. A break-out wire from the switchmode power supply
provides the Clean Pin Alert output signal.
Connection using customer’s own power supply:
It is the customer’s responsibility to check that the 24V power supply they will be using
is grounded. If it is NOT grounded they must check that grounding it via the ground
post on the 971IPS-15 bar will not affect any other systems running from that power
source.
The 24V supply should be protected with a 1 Amp fuse.
Clean Pin Alert - Remote Monitoring
Remote monitoring of the need to clean the bar is provided by the output signal on
pin 2. The signal is 0V-24V suitable for direct connection to a PLC input. The output
impedance of the signal is 10kΩ. The output can also be configured to power an
external relay to provide volt-free contacts for other monitoring systems.
Using a BarMaster remote programmer the output can be set to Normally Open
(factory default) or Normally Closed.
