4.2.8 Integrated Protection Serial
Interface Type D (IPSI-D) (Optional)
The ISPI-D is an optional unit that converts the
IPD’s communication protocol into the
Ampcontrol IP2 Protocol. A DNET-IP2 Protocol
Converter can then be used to convert the
Ampcontrol IP2 Protocol into RS232, RS422 or
RS485.
This communications system allows external
devices, such as PLCs, to communicate with the
IPD relay.
For more information on the DNET-IP2
Communication System, refer to the separate
user manual for this product:
DNET-IP2 Serial
Communication System User Manual
.
4.2.9 Earth Fault Test Module (EFTM)
(Optional)
The Ampcontrol EFTM can be used to test the
operation of the IPD’s earth fault lockout (EFLO)
protection. This connection is made between the
CCMD and the IPD, via a three (3) pole relay. The
EFTM is connected between this relay and earth.
To test the operation of the EFLO protection, the
relay is held closed during an attempted start of the
outlet. The IPD will sense the resistance to ground
and will trip on EFLO, preventing the outlet from
starting.
4.2.10 CCM Load Module (Optional)
The CCM Load Module is an optional unit that should
only be installed if the user is experiencing spurious
Main Contactor Fail (MCF) trips due to induced and
electrostatic noise pick-up.
The CCM Load Module is designed to reduce spurious
MCF trips which may occur in 3.3kV systems by adding
a parallel resistance to the CCMD, reducing total
impedance and improving noise immunity. The Module
forms part of the overall integrated protection system,
working with existing outlet protection.
