2 RECEIVING AND STORAGE
2.1 Receiving
All possible precautions are taken to protect the equipment against damage or losses during shipment;
however, before accepting delivery, check all items against the packing list or bill of loading. If there is
evidence of physical damage, notify Ampcontrol immediately.
Notify Ampcontrol immediately in the case of any discrepancies to the packing list. Keep a record of any
claims and correspondence. Photographs are recommended.
Where practicable do not remove protective covers prior to installation unless there are indications of
damage. Boxes opened for inspection and inventory should be carefully repacked to ensure protection of
the contents or else the parts should be packaged and stored in a safe place. Examine all packing
boxes, wrappings and covers for items attached to them, retain and store any approval documentation
for your safety file as applicable prior to wrapping being discarded.
2.2 Inspection
Equipment that is found to be damaged or has been modified away from its published specification must
not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or
if it does not match the published specifications.
2.3 Storage after Delivery
When the equipment is not to be installed immediately, proper storage is important to ensure protection
of equipment and validity of warranty.
All equipment should be stored indoors between 0 to 50˚C, preferably on shelves and protected from
moisture and sunlight.
2.4 Unpacking of Equipment
The method of packing used will depend on the size and quantity of the equipment. The following
cautions should be interpreted as appropriate.
CAUTION!
Take care when unpacking crates as the
contents may have shifted during transport.

3 PRODUCT OVERVIEW
3.1 Description
The Ampcontrol PF1 is a multi-functional Relay designed for hard rock mining applications. It has the
ability to perform two standard protection functions which are compliant to AS/NZS2081:2011 for Earth
Leakage and Earth Continuity. In addition to these protection functions, the PF1 also provides selectable
control functionality for Pump or Fan motor installations.
The Pump Protection function manages the no-load/under-current condition of a pump by monitoring the
load current. When the load on the pump motor decreases due to the intake pipe not being fully
submerged (known as snoring), the speed of the pump motor will rise to its maximum, which can burn
out the pump motor in as little as 30 seconds. The under-current condition is detected by the PF1 which
can apply a configurable sleep/run cycle to help prevent pump burnout due to a lack of water.
The Fan Protection function manages the gradual pre-inflation of flexible ventilation conduit, by applying
a pulsed (burp) start-up sequence to the fan motor. This can prevent damage to the material of the
ventilation tube during the initial stages of inflation.
The four protection/control functions of the PF1 can be independently enabled or disabled as required.
3.2 Features
The PF1 has the following key features:
Fully configurable using Smart Tools PC software, via USB (external power not required)
Pump Protection (Anti-Snore Mode)
Fan Protection (Burp Mode)
Earth leakage protection (AS/NZS 2081:2011 compliant)
Earth continuity protection (AS/NZS 2081:2011 compliant)
Remote start/stop functionality
Event data logging (10,000 records)
24Vac or 24Vdc operation (one model)
DIN rail mounted
LED status indication to aid in diagnostics
Pluggable screw terminal blocks
3.3 Application
The PF1 is intended for use in the hard rock mining industry on electrical outlets supplying Pump or Fan
motors. When applied correctly, the specialised pump and fan protection functions can significantly
reduce the risk of damage to equipment and thus can also considerably reduce maintenance
requirements.
The PF1’s Pump and Fan operating functions can both be disabled, allowing the PF1 to also operate as
a combined Earth Leakage and Earth Continuity relay on non-pump and non-fan outlets. This has the
added advantage of reducing Relay variants used across a given site (reduced stock, spares,
maintenance and operator training costs).
The following sub-sections provide some typical applications of the PF1.

4 INSTALLATION
4.1 General Warnings
These instructions have been designed to assist users of the PF1 with installation.
Before the PF1 can be installed, there are a number of things that need to be considered and
understood to prevent incorrect or unsafe operation of the PF1 or the system into which it is installed.
Along with relevant competence, and an understanding of the target application, the following points
should be considered:
Ensure that the information provided in this user manual is fully understood.
It is extremely important that the functionality and any limitations of the PF1 are understood to prevent
incorrect installation or usage creating a potentially dangerous hazard.
Ensure that the application into which the PF1 is being installed has been properly
specified, designed and approved.
Any system intended to mitigate the risk of injury needs to be properly designed and implemented.
Such a system must be the result of structured risk analysis with the outcomes used to define the
system requirements. These requirements, in turn, will guide the choice of instrumentation, logic
solvers and actuators needed to implement the system. Understanding the needs of the system will
ensure proper selection of equipment.
Ensure that the PF1 will properly perform the required functions within the system
design.
It is important to understand how the PF1 is intended to interact with other equipment within a system.
For safe and reliable use, it is crucial that neither the PF1 relay’s logical operation nor its signalling be
compromised by incompatibilities with connected equipment.
WARNING!
The PF1 has been designed to provide the user with the maximum
flexibility, with regards to configuration. The user is able to configure the
PF1 such that the Earth Leakage and Earth Continuity protection
functions are disabled.
Ampcontrol accepts no responsibility or liability in cases where
the user has incorrectly configured the PF1. The user remains
ultimately responsible for the configuration of the PF1 and their greater
system.
Modifications of any form to the PF1 are prohibited.
The PF1 as supplied has been designed and manufactured to comply with the requirements of
protection standards. If modifications of any form are made to the PF1, the equipment may no longer
be fit for use. If any modifications or damage to the PF1 is evident, do not use the equipment.

Vs Earth (Terminal 3)
The Vs Supply Earth must be connected to a frame or common earth via a minimum 1.5mm2
conductor.
VDC Out (Terminals 4)
Output voltage source, used in conjunction with the digital inputs.
Digital Inputs (Terminals 5, 6, & 7)
The PF1 has three (fixed) digital input terminals: Reset (N/O), Start (N/O) & Stop (N/C), respectively.
To wire in a digital input, the contact of the actuator must be wired between the VDC terminal (4) and
the input’s terminal. When the contact closes, the VDC voltage will be applied to the input terminal,
thereby “closing” the input.
The PF1 relay’s digital inputs are intended to be wired to the output contacts of a PLC and/or to
external pushbuttons.
NOTE
The maximum allowable loop impedance for each of the digital inputs is
1kΩ. Ensure that the impedance at the time of installation is sufficiently
under this, such that any circuit degradation over time –due to contact
deterioration, oxidisation etc. –will not increase the impedance above
this limit.
PI1 Input (Terminal 8)
Programmable input 1.
This input is able to be programmed to different uses from within the PF1’s Smart Tools software. See
Section 11.4 for further details.
NOTE
The maximum allowable loop impedance for the PI input is 1kΩ. Ensure
that the impedance at the time of installation is sufficiently under this,
such that any circuit degradation over time –due to contact
deterioration, oxidisation etc. –will not increase the impedance above
this limit.
Terminals 9, 10 & 11
Future use, do not connect anything to these terminals.
K2, K3, K4 Output Relays (Terminals 12, 13, 14, 15, 16 & 17)
The functionality of the K2, K3 & K4 Output Relays can be customised to the user’s requirements using
the Smart Tools software. These relays are normally open, but can be individually programmed to
operate as normally closed relays if desired (all relays will revert to normally open on Vs power loss).
These output relays are primarily intended to be used to switch indication circuits into PLCs and
Lamps. Depending on the application, they can also be used to add a level of redundancy to the
operation of K1.
Refer to Section 11.5 for further details.
