Eriez X8 User manual

X8 METAL DETECTOR
REFERENCE GUIDE
2023810A (sw pkg 1.0.0)

Use this product only in the manner described in this manual. If the
equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
CAUTION
The metal detector is heavy. Do not lift nor support the metal
detector by hand/manually.
To avoid damage or injury, use only the handling and installation
procedures outlined in this reference guide.
CAUTION
Hazardous voltages are present in this equipment when energized.
All power sources must be isolated or disconnected before
accessing the inside of the enclosure.
Failure to follow these precautions may result in serious injury or
death.
WARNING - HAZARDOUS VOLTAGE
If you have a pacemaker or other implanted medical device, please
consult your doctor before using this product. Electromagnetic
waves can interfere with the operation of your pacemaker or other
medical devices.
CAUTION
Metal detectors emit electromagnetic fields, which may interfere
with some pacemakers or other implanted medical devices. The end
user bears the responsibility to determine if the emitted
electromagnetic fields will affect employees with medical devices. If
you have an implanted medical device, please consult your doctor
before being in the vicinity of the metal detector during operation.
CAUTION
1

To avoid injury or damage to the equipment, only qualified service
technicians are to install the metal detector at customer sites in
accordance with local safety codes.
CAUTION
To avoid injury or damage to the equipment, all electrical
installations are to be performed by qualified and competent
personnel authorized by Eriez Manufacturing Company. All electrical
installations are to be in compliance with local safety codes. Ensure
that all materials used in the installation of the equipment are
suitable and appropriate for purpose.
CAUTION
For continued compliance with electrical safety standards, the
protective earth connection from the power source must be
connected directly to the protective terminal on the wall of the
enclosure. This is required to be the FIRST connection to the
terminal, and secured with a star lock washer and nut, independent
of any other connections to the terminal.
CAUTION
An external disconnect switch labeled “Metal Detector” must be
installed near the metal detector to allow the metal detector to be
completely disconnected from the power source during installation
and maintenance. All lock-out tag-out procedures and local safety
codes are to be followed during metal detector installation and
maintenance.
The metal detector must not be positioned in a way that makes it
difficult to operate the disconnect switch.
CAUTION
2

Cleaning procedures may cause false trips of the metal detector,
resulting in actuation of any connected reject devices. Ensure
personnel and equipment are clear from the path of the reject
devices at all times. To avoid an unsafe condition or damage to
equipment, remove all power sources (including air supplies) from
the metal detector and reject devices prior to wash down.
CAUTION
To avoid injury or damage to the equipment, all electrical
maintenance on the metal detector is to be performed by qualified
and competent service technicians authorized by Eriez
Manufacturing Company.
CAUTION
The X8 metal detector is not designed nor intended for operation in
environments classified as hazardous locations/zones. Do not
operate the X8 metal detector in areas where the possibility of
explosions or fires exists.
CAUTION
For installations where the metal detector control screen presents
ergonomic challenges or unsafe viewing conditions, it is
recommended that a remote display be used to eliminate these
issues.
CAUTION
The metal detector will start automatically when power is restored
after a power interruption. All external components controlled by
relays within the metal detector control will also complete their
cycle when the metal detector is re-energized. The end user must
determine if a hazard exists and install the proper safety precautions
and protocol to ensure that an injury does not occur in the event of
a power interruption.
CAUTION
3

When cleaning the metal detector surfaces, use appropriate personal
protective equipment (PPE) for any physical/chemical/biological
hazards that may exist due to the end user’s production
environment. Avoid contact with contaminants on or around the
metal detector. Pressure Wash and sanitize metal detector surfaces
when maintenance is required.

HANDLING
RF INTERFERENCE
Radio Frequency (RF) emissions have been tested to the requirements of FCC 47CFR
Part 15B, FCC 47CFR Part 18, and CISPR 11/EN 55011 (Class A, Group 1). The Eriez
X8 Metal Detector generates an electromagnetic field, which has the potential to
escape. This field may interfere with nearby radio frequency equipment.
If interference becomes a problem, you may need to:
1. Move the Metal Detector or interfering equipment
2. Change the frequency on the Metal Detector
3. Call the Factory for further assistance
HANDLING INSTRUCTIONS
DO NOT LIFT THE METAL DETECTOR BY INSERTING ANYTHING INTO OR
THROUGH THE TUNNEL.
The inner surface of the tunnel protects the precisely tuned electronic circuit and
internal parts. The tunnel liner also protects the internal parts against water damage.
The integrity of this liner and seal must be maintained. Any damage or distortion to this
surface caused by handling will invalidate the warranty.
When handling, keep the metal detector on the shipping pallet as long as possible.
WHEN REMOVING THE DETECTOR FROM THE SHIPPING PALLET, LIFT ONLY ON
THE DETECTOR HOUSING SURFACES OR SUPPORTING FEET. DO NOT LIFT BY
THE CONTROL HOUSING THAT PROTRUDES FROM THE BODY OF THE METAL
DETECTOR.
If possible, lift the metal detector by using a crane and soft nylon slings running under
the entire metal detector housing as seen below. See Vertical Metal Detector with
Valve Addendum at the end of this reference guide Pg.90 for information concerning
vertical metal detectors.

Figure 1: Metal detector handling instructions

Larger metal detectors may have eyebolts preinstalled at the factory. When handling
with the eyebolts ensure loads are never applied perpendicular to the shank of the
eyebolts; they will break.
The metal detector is heavy. Do not lift nor support the metal
detector by hand.
To avoid damage or injury, use only the handling and installation
procedures outlined in this reference guide.
CAUTION
Never weld any attachment to the metal detector. Do not attempt to drill and/or tap
the metal detector for lifting or mounting attachments.

SPECIFICATIONS
EQUIPMENT DESCRIPTION
The Eriez X8 Metal Detector is a balanced coil metal detector used to detect metal
contaminants/foreign objects in material(s) passed through the aperture.
SUPPLY, MAINS, VOLTAGE
The X8 Metal Detector will operate from AC supply voltages over the range of 100 to 240 VAC
RMS, 50 or 60 Hz. Mains supply voltage fluctuations shall not exceed ±10% of the nominal
value.
EQUIPMENT CLASSIFICATION
The X8 Metal Detector is specified for the following categories:
-Class 1 equipment requiring a protective ground conductor.
-Installation Category (Overvoltage Classification) II
-Pollution Degree 2
MAXIMUM DEMAND
The internal electronics require 60 VA to operate. The power available for external loads
(powered from the internal source) is 1250 VA and is limited to 5 amps of current by CB2.
Maximum demand will be 1310 VA.
OUTPUTS
There are nine total outputs, each with one set of contacts. There are four programmable “Form
C” (NO-C-NC) relay outputs rated at 5A (due to PCB trace width) up to 250 VAC, 30 VDC each.
-Reject (K1)
-Relay 1 (K3)
-Relay 2 (K2)
-Relay 3 (K4)
All four relays are fail-safe wired; if power is lost, the relays will switch to the activated position.
NOTE:If the power at L1B and L2B is used to power the relays, its maximum available current
is 5A, and the voltage will be equal to that applied at L1 and L2 on TB3.
