hazardous areas (NEC Article 504,
Intrinsically Safe
Systems ) published through the Instrument Society of
America.
The UMC 600IS is a Factory
Mutual-approved system. This
approval is valid only if the
installation conforms to the
guidelines described in this manual. If
modifications are made to the installation procedure, the
enclosure is opened, or the instrumentation is changed in
any way, Factory Mutual approval is void and the

1.0 Introduction
The UMC 600IS is a single-channel digital weight indicator designed and approved to operate as an intrinsically
safe system in a wide variety of scale and weighing applications. The indicator is housed in a NEMA 4X
stainless steel sealed case. The standard unit is equipped with a tilt stand base for tabletop or wall mounting
applications. The indicator front panel consists of a 21-button keypad, six digit, seven-segment display and 11
LED annunciators (see Figure 1-1 on page 2).
Features of the UMC 600IS include:
• Full front panel digital configuration and
calibration
• Zero and span temperature compensation to
ensure compliance with NTEP temperature
range requirements (–10 to 40°C)
• Nonvolatile memory stores data for
calibration, temperature compensation,
configuration parameters, auto or fixed tare
values, and PAZ and AZM values
• T en-thousand displayed graduations;
80,000 graduation expansion available
NOTE: Use of more than 20,000 graduations may cause
undesirable display instability in some applications.
• Analog sensitivity to 0.3 µ V/grad at 20,000
graduations
• Ten updates per second, with selectable
digital averaging and auto averaging; 5 Hz
active analog filter for smooth response
• Excitation for four 350 Ω load cells at 5 VDC
• Operable from DC power supply or optional
battery
• Time and date print selection
1.1 Factory Mutual Approval
The UMC 600IS is Factory Mutual (FM) approved
for:
• Classes I, II, and III,
• Divisions 1 and 2, and
• Groups A, B, C, D, E, F and G
The Factory Mutual (FM) approval is a system
approval for all devices connected directly to the
UMC 600IS digital weight indicator.
Other devices that have FM Entity Approval cannot be
used with this system unless specifically listed in this
manual as part of the Condec Factory Mutual systems
approval. Failure to comply with this voids the FM
approval. The control drawing is the guide to the
installation of this system.
