Introduction
This assembly and operating manual is intended for
use by service technicians responsible for installing
and servicing the RL1100EM mechanical-to-
electronic conversion kit.
The kit comes complete with an IQ plus
®
390-DC
indicator, a RL20000 S-beam load cell and all
necessary conversion hardware.
The IQ plus 390-DC is a single-channel digital weight
indicator housed in a NEMA 4X/IP66-rated stainless
steel enclosure. The indicator front panel consist of a
1 inch (25 millimeter), six-digit, liquid crystal display
(LCD) and six-button keypad. The indicator comes
with a pre-drilled mount bracket for easy installation
and assembly.
The indicator features include:
•
Electronic data processing (EDP) port for full
duplex, RS-232 communications up to 19200
bps
•
Powered by six C-size batteries for complete
portability
•
AC adapter for 115 or 230 Vac power;
•
Standby mode which can be configured to
limit indicator power consumption when scale
is inactive
•
Piece count mode for basic parts counting
functions
The IQ plus 390-DC is NTEP-certified for Classes III
and IIIL operation at 10,000 divisions.
The RL20000 load cell is an S-beam, nickel-plated,
alloy steel load cell that has a full-scale output of 3.0
mV/V and a nominal bridge resistance of 350
Ω
.
