6.
With the “v” showing press the lock push
button. The “v” then changes to “E”. (This is
a prompt to press the enter key).
7.
Press the enter key. At that instant, the seconds
are zeroed and the selected time/date
information is transferred to the internal clock.
If the battery voltage is low the time will zero and the
date will reset to 1st January on power up. If the
battery is flat or faulty the relay is likely to trip on
main contactor fail on power up.
Note: The date and time are used only to time stamp
the events in the log (which are recorded sequentially
regardless of the date/time). Date and time data is not
used for any control functions.
11. Remote Data Communications
The IPC Integrated Protection Relay has the facility
for connecting remote monitoring equipment. This
can be in the form of either the Remote Display
Module or other peripheral equipment such as
PLC’s.
For PLC applications each integrated protection relay
is connected to a Serial Interface Module (IPSI),
which has its output drop connected to a DNET-IP2
Protocol Converter. The Protocol Converter provides
the communications link to a PLC (See User Manual
E06510 for further details).
The Ampcontrol DNET-IP2 Serial Communication
System transfers data and commands between the
Host System and the modules using RS232, RS422
and RS485 protocols.
12. Installation & Wiring
Instructions
The IPC Integrated Protection Relay is a
microprocessor based protection relay that has the
facility for connecting intrinsically safe remote
monitoring equipment. This can be in the form of
either the Remote Display Module or other peripheral
equipment such as PLC’s.
These instructions have been designed to assist users
of the IPC Relay with installation and special wiring
techniques required maintaining the integrity of the
intrinsically safe circuits.
12.1 Installation
(A) IPC Integrated Protection Relay
The IPC Relay has a powder coated sheet steel
enclosure designed to be mounted into existing
enclosures, ie flameproof equipment or other
enclosures of adequate IP rating.
The relay is designed to operate when mounted either
laid down flat or in a vertical position. Vent holes are
provided at both the top and bottom of the relay to
assist in the cooling of the electronics inside the relay.
These vents should not be blocked or restricted in any
way.
When installing the IPC Relay care should be taken
to ensure sufficient space is allowed around the relay
for the ease of change out during routine
maintenance.
Connections to the IPC Relay are made via a plug in
base. This base is to be securely fastened to the
enclosure in which it is being installed. The base is
clearly labelled for ease of terminal location and
identification. The base sockets are factory adjusted
so that they are able to move to assist in alignment
when the relay is inserted.
Do not tighten socket
mounting screws. For installation mounting see
drawing IPBA029 (Page 35)
(B) Remote Display Module (RDM)
The Remote Display Module is an intrinsically safe
device (Ex ia), designed to be mounted into the cut
out of an IP54 enclosure and can therefore be
mounted external to the switchgear it is controlling.
To provide maximum benefit to the operator, one
RDM is normally used per relay. This allows
information from several relays to be simultaneously
accessed and compared. However, if space
restrictions preclude this, a compromise is to use one
(1) RDM to monitor and control more than one IPC
Relay. In these circumstances the following wiring
arrangement is recommended:
RDM1
IPB1
IPB2
The 3 pole change over switch must have sufficient
creepage and clearance between IPC Relay channels
in accordance with AS2381.7, 1989, Section 3.
(C) CCMC Cable Connection Module
The Cable Connection Module (CCMC) is a resistor-
diode barrier, which interfaces between the power
circuit and the IPC Relay. It also provides an
automatic High Voltage DC ‘Insulation Test’
following a successful Intrinsically Safe Earth Fault
Lockout Test. The CCMC is housed in an
encapsulated module.
