2.0 Introduction
The PULSAlarm® ® is a microprocessor based stroke length control device for use with
the PULSA diaphragm-metering pump. It has been designed to operate in a variety of
industrial environments.
3.0 Foreword
The pumps to which these “instructions” refer to are designed for use in industrial areas
and therefore cannot be treated as retail products. The present documentation gives
instructions to be used by qualified personnel only. It must be used in compliance with
the regulations, laws and technical standards in force and cannot, under any
circumstances, take the place of plant standard or additional regulations, including any
which are not legally enforceable, which have been issued with the scope of ensuring
safety.
Equipment with special manufacturing or constructive variances may differ in details with
respect to this description.
In case of any difficulty, please contact PULSAFEEDER, INC. Technical Service.
The PULSAlarm® is rated for NEMA 7 locations as identified on the nameplate.
The PULSAlarm® complies with both ATEX and IEC IECEx standards.
The following standards apply to this product:
IEC 60079-0 6
IEC 60079-1 6
IEC 60079-31 1
EN 60079-0:2012+A11:2013

4.0 ATEX / IECEx Nameplate and Marking
All pumps bear a standard rating nameplate on which it is possible to read, apart
from functional data, all data required for universal identification.
Conduit connections
Conduit connections can carry fluids and vapors into the PULSAlarm®
causing damage and void the warranty. Care should be taken when
installing conduit to protect against fluid/vapor entry. In accordance with
any applicable codes provide sealed entries and conduit drains near the
point of entry as required. For installation purposes, the conduit glands on
the PULSAlarm® are .50-14 NPT.
To reduce the risk of ignition of hazardous atmospheres, conduit runs must
have a sealing fitting connected within 18 inches of the enclosure for
Division applications. For Zone applications, a seal shall be installed within
50 mm of the enclosure.
