1 Safety instructions
1.1 Designated use
The MPC series level controllers are displacement type instruments for installation on tanks. It provides control
outputs from 1 to 4 contacts while activating microswitches
with a magnet. Switching mechanism is designed to operate these contacts independent of one another.
The instruments could therefore emit high and low alarm signals. It also performs pump control by utilizing the
independent operations of the contacts
1.2 Installation, commissioning and operation
• Mounting, electrical installation, start-up and maintenance of the instrument may only be carried
out by trained personnel authorized by the operator of the facility.
• Personnel must absolutely and without fail read and understand this Operating Manual before
carrying out its instructions.
• The instrument may only be operated by personnel who are authorized and trained by the operator
of the facility. All instructions in this manual are to be observed without fail.
•The installer must make sure that the measuring system is correctly wired according to the wiring
diagrams. The measuring system is to be grounded.
1.3 Product Requirements
Connection to the peripheral equipment
It is possible to connect to the peripheral equipment explained in this installation Instrumants. Please refer to
each installation Instrumants when connecting.
1.4 Safety of operation
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex documentation",
which is an integral part of this Operating Manual. Strict compliance with the installation instructions and
ratings as stated in this supplementary documentation is mandatory.
•Ensure that all personnel are suitably qualified.
•Observe the specifications in the certificate as pipe as national and local regulations.
FCC approval
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Caution!
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.

1.5 Notes on safety conventions and symbols
In order to highlight safety-relevant or alternative operating procedures in the manual, the following
conventions have been used, each indicated by a corresponding symbol in the margin.
Safety conventions
Warning!
A warning highlights actions or procedures which, if not performed correctly, will lead to
personal injury, a safety hazard or destruction of the instrument
Caution!
Caution highlights actions or procedures which, if not performed correctly, may lead to
personal injury or incorrect functioning of the instrument
Note!
A note highlights actions or procedures which, if not performed correctly, may indirectly
affect operation or may lead to an instrument response which is not planned
Explosion protection
Device certified for use in explosion hazardous area
If the device has this symbol embossed on its name plate, it can be installed in an explosion
hazardous area
Explosion hazardous areas
Symbol used in drawings to indicate explosion hazardous areas.
– Devices located in and wiring entering areas with the designation
“explosion hazardous areas” must conform with the stated type of
protection
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas.
– Devices located in safe areas still require a certificate if their outputs run into explosion
hazardous areas
Explosion protection
Direct voltage
A terminal to which or from which a direct current or voltage may be applied or supplied
Alternating voltage
A terminal to which or from which an alternating (sine-wave) current or voltage may be
applied or supplied
Grounded terminal
A grounded terminal, which as far as the operator is concerned, is already grounded by
means of an earth grounding system
Protective grounding (earth) terminal
A terminal which must be connected to earth ground prior to making any other
connection to the equipment
Equipotential connection (earth bonding)
A connection made to the plant grounding system which may be of type e.g. neutral star
or equipotential line according to national or company practice

4.2 Overflow alarm
There are two specifications: displacer for CRT and weight type for FRT.
When displacer or weight reached set position, alarm signal is output to warn of overflow.
The operation and performance are same as 1 switch point type MPC. When liquid reaches the upper limit
point, displacer rises and triggers alarm. MPC2 also has a checking function. By pulling the test wire and raising
the displacer manually to the high limit point, an alarm can be simulated.

4.3 Mounting (Ex type)
The MPC are deliverd in four separate parts Body, Spring (include Iron), Displacer, Pipe (Internal,
outer). Please mount them as following and install it on the tank.
Note!
• Please handle the displacer wire with care, as the displacer is connected with wire. It may cause
damage by kink.
• When connecting Displacer and Spring, use the fixed triangular joint with threaded displacer
locknut. Be careful not to move the displacer position because it has already been adjusted at
factory.
• Be careful not to bend intermediate shaft, when mounting spring and body.
• Mount locking screw of spring tight.
• After mounting as follows, connect with pipe.

Alarm contact can change within the length range of wire on which is hanging a displacer. Please move the
displacer position the length and direction that you wish to change. (ex. when going down 100mm upper alarm
contact, go down 100mm the upper displace). Do not touch the switches in the body.
7 Operating and Maintenance
There are no special notes about operating and Maintenance, but if the liquid is adhesive, please clean sealpipe,
displacer, internal pipe.
