2 Design and method of operation
2.1 Functional principle
The metal detector works with the so-called "balanced coil" principle:
The transmitter winding in the search coil creates a high-frequency electromagnetic field, which is received by symmetrical placed receiver windings. The windings are connected against each other;
when undisturbed, the system is in balance.
An electrically conductible object within the detection area disrupts this balance and the electronic creates a switch signal.
A "teach in process” allows to suppress the conductivity of the product itself. Deviations from the
taught-in product are usually caused by metal contaminants, which are detected by the device with
high precision.
The metal detector is equipped with comprehensive test and analysis software to ensure fault-free operation and retracing of product errors.

4. Safety
The following safety and danger notes are intended for your protection, for the protection
of third parties, and for the protection of the equipment. The safety notes therefore should
always be observed!
The equipment is intended for use in the following fields of application and only in combination with a corresponding detection coil of series GLS, C-SCAN DLS, P-SCAN RP: Suction/pressure conveyor applications, free-fall applications, and applications at a conveyor
belt. The equipment can be used in the plastics, food, animal feed, recycling, and chemical
industry. Basically it is possible to also use the system in other applications than the intended use stated herein, but such applications always require the prior consultation and
approval of Sesotec GmbH.

This symbol indicates that mains voltage is used in the electronics housing, and that any connected external circuits
(e.g. at the metal relay) also may be energised. There is
danger of electric shocks due to the presence of mains voltage.

"Metal" (2) und "Fault" (3)
Any non-observance of safety notes constitutes a danger for life and health.
The control unit PRIMUS+ may only be operated in the intended purpose and in a perfect functioning condition, especially the cover of the electronic housing has to be closed during operation. Entered moisture has to be removed! All fixed warning signs on the equipment may not be
removed and have to be in a well recognizable condition. The operating instructions always
have to be in a legible condition and complete available. Prior to commissioning always make
sure that the applicable accident prevention regulations are observed. If the control unit is
not mounted at the detection coil, it must be properly and firmly fastened by means of the
four screws. The operator must make sure that the equipment is mounted at an ergonomic
height for operation. The operator may only appoint qualified personnel for operation, mainte-
nance and repair work. If potentially explosive materials are examined, the pertinent regulations must be observed.

Our equipment conforms to all official technical safety regulations. However, as a manufacturer we believe it is our duty to make you aware of the following information.

4. Safety
detector or separator does not exceed the limits stated in the provisions. Therefore there
are no health impairments due to electromagnetic fields in this area for persons and for
wearers of medical implants such as cardiac pacemakers. Inside the coil of round or
closed tunnel coils, or on the surface of flat coils, the limits may be exceeded depending
on design and system version. If work is to be performed inside or at the search coil, persons and wearers of medical implants such as cardiac pacemakers may only enter the
equipment when it is turned off, provided that size and design allow this.
Because of energised components in the electronics housing there is a risk of injuries due
to electric shock or burns. During operation the cover of the electronics housing must be
kept closed. Only qualified personnel may operate and clean the equipment.
If the electronics housing must be opened for maintenance or cleaning purposes, remove
any dirt and moisture from the electronics housing, so that no larger amounts may get into
the interior. Always disconnect the power supply and any connected external circuits before opening the cover. Any moisture that has penetrated into the interior must be removed from the electronics housing. If any maintenance work must be performed in
energised condition, e.g. battery replacement, such work may only be performed by a
qualified electrician under strict observation of the attached warning labels and with due
regard to standard approved rules of electrical engineering.
No safe condition is established when outputs are switched "inactive" (with "Disable Outputs", "Bypass", or "Output level inactive".
For any maintenance work the compressed-air and power supply of the machine must always be disconnected, and any existing pneumatic cylinders must be vented.
To avoid any injuries due to energised parts in the electronics housing, the information in
5.1 and 5.2 must always be observed.
Always observe the information in paragraph 10 to avoid any transport damage and personal injuries.
Electrical circuits may still be live even after having been isolated from the mains. Switch
off immediately if a fault occurs.
To avoid any loss of stable standing, the information for transport, commissioning and operation must always be observed. Always make sure that the fastening screws of the control unit are tight during operation. When storing or transporting the control unit, place it on
the closed rear panel of the housing.
Unauthorised modification or repair will invalidate all manufacturer declarations and guarantees.

4. Safety
For other applications as enumerated in 4.1 the control unit PRIMUS+ intended for – that
is regarded as inadmissible operation. Improper use also includes operating the equipment with excessive mechanical, static or dynamic loads (e.g. heavy machine parts or
strong vibration). It is furthermore not permitted to inspect any aggressive materials on the
conveyor, such as materials containing lyes, acids, and solvents, or materials that react to
electromagnetic fields, or living persons or animals, and to operate the system in an Ex
protection area.

5.1 Mechanical mounting
Ensure stable and non-vibrating installation! In house mounting and operation. Do not install the
system in an explosion proof zone.
Do not install the detection coil and the electronic unit in the vicinity of interference fields (large
electric motors and frequency converters!) The distance depends on the power consumption of the
motor or of the frequency converter (value for orientation: 5 m).
Mount the control cabinet by using the provided bores. I.e. at a wall or frame (dimensions are shown in
the outline drawings). Pay attention to good stability, as the weight of the control unit is approx. 4 kg.
Never install the electronic unit in other switchgear cabinets, because this may lead to interference
effects. (E.g. from contactor controls)!
Cable lengths may only be modified after consultation with "Sesotec". Use only original cables. Lay
the connecting cable in fixed installation apart from other cables (e.g. fix it with nailing clips or lay it
in a cable duct).
If several metal detector systems are used, the distance of the detection coils must not be less than
2m, if these coils stand side by side. If the coils are arranged opposite to each other, the distance
must not be less than 10 m. These values apply to large systems; for smaller systems the distances may be reduced to 50 cm. If, for reasons of space, these distances cannot be observed, please
contact Sesotec service!
Do not install the equipment in such a way that operation of the mains cut-off switch is hindered in
any way!
