INTRODUCTION
The VAAFH AC/DC is an ideal monitor system for 240/120
generators and grid power sources and provides monitor of
load balancing on the 120 VAC legs. Additionally, the AC/
DC model now provides DC volts and amps monitoring. This
meter meets NFPA requirements 1901 22.4.6.3 for monitoring
of permanently mounted generators on fire apparatus.
It provides accurate digital metering for AC Volts, Amps,
Frequency and logs generator hours. Low/High Voltage,
Amperage and Frequency alarms are easily set. When
activated, the built-in 85 dB alarm will sound and the affected
display reading will change RED for the out-of-limit condition.
The meter is waterproof and rugged with a large color LCD
display screen read-out divided into 6 display sections allowing
the operator quick, and accurate assessment on the state of
the generator output and applied loads.
AC volts are displayed from 90 to 300 VAC and DC volts to 33
VDC, 300 amps max. Two Amperage readouts for both 120V
legs of the 240 circuit are displayed from 0 to 150 amps, and
Frequency is also displayed. Generator hours are logged and
easily viewed via menu selection.
The meter is powered from 12-24VDC. Four levels of
backlighting can be selected and the display can be remotely
turned ON/OFF. All set-up, calibration and alarm values are
saved to non-volatile memory. The system is complete with DC
amp shunt, voltage and current transformers, and is factory
calibrated to read within 1%. The large LCD display draws only
0.08 amps with full brightness and only 0.02 in sleep mode.
INSTALLATION
Before starting the installation, please read this entire
section first
The meter is designed for panel mount in a 2-1/8 hole.
Locate a suitable position for the meter, (refer to applicable
NFPA regulations) cut mounting hole 2-1/8” (55mm) where
you desire to mount the instrument (Figure 1) and secure
in position, the gasket provided ensures a waterproof seal
against the mounting surface. (Caution it’s important that the
spacing nuts (2) contact the underside of the mounting bracket.
Do not over tighten the mounting nuts). Finger tighten the
screws that mount the instrument bracket. It is not necessary
or recommended to use tools.
