Key Functions
The
6
,
+
,
5
(
V
,
A
,
F)
and
*
keys are used to select what to
display, set backlight levels, calibrate volts/amps/frequency,
turn alarms on/off, set alarms and set/change constants. New
information is automatically saved to non-volatile memory.
Turning Alarms ON/OFF
Press the
5
key 1/2 second to turn alarms ON. In Voltage mode,
the alarm icon will light. Press the
6
key 1/2 second to turn the
alarms OFF.
Backlight Intensity
Press
+
the key 1/2 second to adjust the backlight level for night
viewing. Each time you press the
+
key 1/2 second, the level will
get brighter 1, 2, 3, 4, OFF, 1, 2, ... etc. The blue backlight ON/
OFF control wire in cable #2 must be switched to +12/24V for the
backlights to work.
Display Volts/Amps/Frequency/kW
Quick press the
V
,
A
, or
F
key to select Voltage, Amps or Frequency
display. To display Killowats, press the
V
and
A
keys simultaneously.
Setting High Volts Alarm
While viewing Volts, press and hold the s key for ten (10) seconds until you
hear a long beep. The High Volts alarm value will be displayed. Use the
6
and
5
keys to set the desired alarm value. Press the
+
key to save the
High Volts alarm value to memory.
Setting Low Volts Alarm
While viewing Volts, press and hold the q key for ten (10) seconds until you
hear a long beep. The Low Volts alarm value will be displayed. Use the
6
and
5
keys to set the desired alarm value. Press the
+
key to save the
Low Volts alarm value to memory.
Setting High Frequency Alarm
While viewing Frequency, press and hold the p key for ten (10) seconds
until you hear a long beep. The High Frequency alarm value will be
displayed. Use the
6
and s keys to set the desired alarm value. Press the
+
key to save the High Frequency alarm value to memory.
Setting Low Frequency Alarm
While viewing Frequency, press and hold the q key for ten (10) seconds
until you hear a long beep. The Low Frequency alarm value will be
displayed. Use the
6
and
5
keys to set the desired alarm value. Press
the
+
key to save the Low Frequency alarm value to memory.
Setting High Killowatts Alarm
Press the V and A keys simultaneously to view the kW display. While
viewing kW, press and hold the s key for ten (10) seconds. You will hear a
beep and the High kW alarm value will be displayed. Use the q and p keys
to set the desired alarm value. Press the Ì key to save the High kW alarm
value to memory.
Calibrating the Voltmeter
The VAF110 is calibrated at time of manufacture, but can be calibrated
using the front panel keys. To calibrate the voltmeter, press and hold the V
and * keys for 10 seconds (until you hear a long beep) to enter into voltage
calibration mode. Use the q and p keys to make the displayed value read
correctly. Press the
+
key to save the calibration data to memory.
Auto-Zeroing the Ammeter
Press the A key to display amps. Then press and hold the A key for 10
seconds (until you hear a long beep) to auto-zero the ammeter.
Calibrating the Ammeter
To calibrate amps, press and hold the A and * keys for 10 seconds (until
you hear a long beep) to enter into amps calibration mode. Pass a known
amount of current through the current transformer (CT) and use the
6
and
5
keys to make the displayed value read correctly. Press the
+
key
to save the calibration data to memory. A reasonably high value of current
should be used (30 amps minimum) to obtain an accurate calibration.
Calibrating Frequency
To calibrate frequency, press and hold the F and * keys for 10 seconds
(until you hear a long beep) to enter into frequency calibration mode. Using
a known frequency, press the
6
and
5
keys to make the displayed value
read correctly. Press the
+
key to save the calibration data to memory.
NMEA 0183 Sentences
The VAF110 outputs serial data of voltage, amps, frequency and kW in
NMEA 0183 format. The sentences are output in the following formats:
Volts: $IIXDR,U,xxx,V,VAF30,*CS
Amps: $IIXDR,I,yyy,A,VAF30,*CS
Frequency: $IIXDR,F,zz.z,H,VAF30,*CS
kW: $IIXDR,G,aa.a,,VAF30,*CS
*CS = Check Sum
Selecting NMEA 0183 or External Alarm Output
The NMEA 0183 serial data line can be programmed to function as an
external generator cut-off switch. In this way the generator can be shut
down automatically if the voltage or frequency falls outside the alarm
ranges set by the user.
To toggle the data line between NMEA 0183 and Generator Shut-Off, press
and hold down both the
6
and
5
keys for 10 seconds (until you hear
a long beep). The new output mode is automatically saved to memory. A
5V signal in series with 270 ohms (10 mA Max.) is output to the generator
shut-down circuitry whenever an alarm condition exists and the alarms are
enabled (armed).
Notes and Warnings
a) During calibration or setting of alarm values, pressing and holding down
the
6
or
5
keys will cause the values to scroll faster the longer you hold
down the keys.
