10.9 Entity Requirement
Cable capacitance and inductance plus the I.S. apparatus unprotected
capacitance (Ci) and inductance (Li) must not exceed the allowed
capacitance (Ca) and inductance (La) indicated on the associated
apparatus. If the optional Hand Held Communicator is used on the
Hazardous Area side of the barrier, then the capacity and inductance
of the communicator must be added and the communicator must be
agency approved for use in the hazardous area. Also, the current
output of the Hand Held Communicator must be included in the
current output of the associated equipment.
The barriers may be active or passive and from any certified
manufacturer as long as the barriers comply with the listed entity
parameters.
10.10 Use in dust atmosphere
Dust-tight conduit seal must be used when installed in dust hazard
environments.
10.11 A device which has previously been installed without an
approved IS barrier must NEVER be used subsequently in an
intrinsically safe system. Installing the device without a barrier
can permanently damage the safety related components in the
device making the device unsuitable for use in an intrinsically
system.
11 REPAIR
WARNING: EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY
IMPAIR SUITABILITY FOR USE IN A HAZARDOUS LOCATION.
Only qualified service personnel are permitted to make repairs
No part replacement is permitted on the SVI-II REMOTE.
On the SVI II AP replacement of the Pneumatic Relay, I/P and Cover (with or
without display) are the only field repairs permitted.
Replace ONLY with genuine Masoneilan parts.
Only parts supplied by Masoneilan are permitted. This includes not only the
major assemblies but also mounting screws and "O" rings. No substitutions with
non-Masoneilan parts are permitted.
Detailed replacement procedures are described in the SVI-II AP Quick Start
Guide. The following summary assures the safe operation of the SVI-II AP.
11.1 COVER (DISPLAY)
Make sure that:
The gasket is seated in the groove in the housing flange.
No wires or retaining cable can be trapped under the cover flange.
The flange area is not corroded and the surface is not scared.
The four cover bolts are securely tightened.
Secure the four cover bolts by applying a torque of 55±5 in-lbs.
