SITRANS WM300 MFA Overview
2
SITRANS WM300 MFA is a highly sensitive, dual setpoint motion sensor alarm unit, used with
MSP and XPP probes. The probe detects an increase or decrease in the speed of rotating,
reciprocating, or conveying equipment and sends the information to the SITRANS WM300
MFA. The SITRANS WM300 MFA works with a pre-amplifier which can be internal to the
motion sensing probe or remote from the motion sensing probe.
Pulses generated from the probe are continually compared to the adjustable setpoint. If the
pulse rate is lower or higher than the setpoint, the alarm relays operating in a faiI-safe mode
will de-energize, indicating failure. The relays will not energize until the pulse rate increases
above or below the setpoint.
The relays can be reset automatically or manually. See Motion Failure Alarm (Page 27).
The SITRANS WM300 MFA is configured for a specific application and must be programmed
and hardwired according to application requirements. Unused inputs or outputs have no
effect on the devices specific operation and must not be wired to any other any other
peripheral equipment.

Installing/mounting

3.1 Safety Note
Note
Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
3.2 Location Requirements
The SITRANS WM300 MFA (and RMA or NCT and power supply converter if applicable) must
be mounted in a non-hazardous area that is clean, dry, vibration-free, within the ambient
temperature range, and non-corrosive to the electronics or its enclosure. The cabinet door
should be accessible for viewing and to allow calibration of the SITRANS WM300 MFA.
Consider the probe location carefully before installation. Avoid strong magnetic fields
(50/60 Hz) from nearby power transformers, heater elements, or large industrial motors,
because these can affect the probe’s performance.
An additional remote display can be connected to the SITRANS WM300 MFA for access to the
unit within an enclosure.

Installing/mounting
3.3 Proper Mounting
SITRANS WM300 MFA
10 Operating Instructions, 11/2021, A5E45090709-AC
Note
Do not mount SITRANS WM300 MFA in direct sunlight.
The SITRANS WM300 MFA can be DIN or wall mounted. In a stand-alone enclosure or panel
arrangement, the device can use a power transformer to take AC to DC voltage. An additional
NCT analog output module is necessary to be integrated into the SITRANS WM300 MFA bus
connection and additional RMA depending on the application requirements.
3.3 Proper Mounting
The probe should be mounted onto a vibration free structure using the mounting flange. The
gap between probe and target should be large enough to prevent the target from damaging
the probe. The probe environment must be within the probe's ambient temperature range
and non-corrosive to the probe's body. Refer to Applications (Page 64).
The probe design detects a changing magnetic field, typically caused by a ferromagnetic
target disturbing the probe's magnetic field. Extremely strong magnetic fields (like those
produced by the 30 A/m requirements of IEC 60004-8, Power Frequency Magnetic Field
Immunity test) will be detected and will result in loss of functionality.
