2.0 Installation
2.1 Terminal Assignments
2.2 Typical Wiring Diagrams
See wiring schematic drawings on reverse side of page.
2.3 Mounting
Caution!
Bracket is placed over gauge in reverse fashion for ease of shipping. Bracket
has been designed to remain secured to the gauge upon proper installation.
Once installed correctly, attempts to remove bracket from gauge may result in
damage to the bracket.
See complete drawing with notes on reverse side of page.
Curtis enGage® II instruments are mounted in a 52mm round cutout. Serrations
on the barrel of the gauge, combined with the mounting bracket provided,
insure fast and trouble free installation. To insure proper installation, the 2
locking tabs on either side of the inner diameter of the bracket should aligned
with the serrations on the barrel of the gauge (see drawing above). Next, slide
the bracket over the barrel of the gauge and press it firmly against back of
panel. You should hear the tab sliding over the serrations.
2.4 Interconnect
Curtis enGage® II mates with either an 8-pin Molex connector (Molex pins
P/N 39-00-0039 FOR #18-24 AWG P/N 39-01-2085) or an 8-pin AMP connector
(AMP pins P/N 770904-X FOR #18-24 AWG P/N 794821-1). A preassembled
mating connector kit (Curtis P/N 15369002=Molex , Curtis P/N 17633308-
03=AMP) with crimp-connect terminated wires (approx. 127mm in length)
is also available.
2.5 Product Identification
2.5.1 Programmable Vs. Factory Set Instruments
Curtis enGage® II gauges are
available with or without front panel
buttons. Gauges without buttons are
factory set and cannot be adjusted in
the field. Gauges with buttons have
field adjustable parameters and can be
programmed per section 2.6.
2.5.2 enGage® II & Multifunction Design
Curtis enGage® II products can be configured in a variety of ways to maximize
customer value and efficiency. Because of this feature, the instruction manual
covers a broad spectrum of products. Please note that some sections of the
instructions may refer to functions not included with your instrument.
2.6 Configuring Your Gauge
Access to these operations is sequential in this order. Adjustments of the
following functions can be performed in the Configuration Mode:
1. Time-of-Day Clock
2. Battery Discharge Indicator profiles
3. Maintenance interval
4. Settable hour meter
During configuration, the right button is used to increment. The left
button is used to:
1. Enter a selection;
2. Advance to the next configurable item.
If no change is desired to a specific gauge function, continue to press the left
button until the next desired function is reached.
The time-of-day clock is entered by setting the hours digits between 01 and 12,
then “minutes” digits between “00” and “59”.
The profile of the BDI is settable with the front panel buttons. The Discharge
Full profile (when the gauge will begin calculating ‘discharge’) is adjustable from
1.80 through 2.30 volts per cell (VPC) in 0.01 VPC increments. The Discharge
Empty profile (when the gauge will indicate ‘empty’) is adjustable from 1.50
through 2.20 VPC in 0.01 VPC increments.
The maintenance interval (when the gauge signals that maintenance is due) is
configurable and should be set after the initial installation. The interval can be
set between 1 and 9,999 hours in 1 hour increments.
The settable hour meter can be set to any value between 0 and 99,999 hours.
When the gauge is operational, the total hour meter will begin from this value.
Configuration Notes:
The gauge remains in configuration mode for 30 seconds without input from
the user.
When configuring each function (time-of-day, maintenance interval, etc.), you
must enter in all data for that function for it to be saved. If incomplete data
is entered for a function and the programming mode is timed out (after 30
seconds of no input received by the gauge), the gauge will revert back to what
was previously stored for that item.
If you interrupt the data entry process in the Configuration Mode, the gauge
saves data in those sections already completed. To complete configuration,
re-enter configuration mode (2.6.1) and simply toggle past the completed
sections and resume where you left off.
2.6.1 Entering Configuration Mode
1. Apply main power (9-60VDC) to V+, V–.
2. Apply V+ (9-60 VDC) to Keyswitch Input.
3. Apply V+ (9-60 VDC) to Set-up Enable.
4. Press and hold the left button on the front panel until the entire
display flashes and then release.
2.6.2 Setting the Time-of-Day Clock
The display will flash the two “Hours” digits. Press the right
button to increment by one hour, or hold the button to increment
continuously. When the desired number of hours is reached,
press the left button once. The display will flash the two
“Minutes” digits. Press the right button to increment by one minute or hold
the button to increment continuously. When the desired number of minutes is
reached, press the left button once.
2.6.3 Setting the Battery Indicator Profiles
The display will flash the three digits of the discharge full profile
(factory setting is 2.09 VPC). Press the right button to
increment by 0.01 VPC or hold the button to increment
continuously. When the display reaches 2.30 it will automatically
restart at 1.80 VPC. When the desired reset profile setting is reached, press the
left button once.
The display will flash the three digits of the discharge empty
profile (factory setting is 1.73 VPC). Press the right button
to increment by 0.01 VPC or hold the button to increment
continuously. When the display reaches full it will automatically
restart at 1.50 VPC. When the desired reset profile setting is reached, press the
left button once.
2.6.4 Setting the Maintenance Interval
The display will flash the left digit (thousands of hours). Press
the right button to increment by one or hold the button to
increment continuously. When the desired number is reached,
press the left button once to proceed to the next digit.
Repeat this process for all 4 digits.
2.6.5 Setting the Total Hour Meter
The display will flash the left digit (tens of thousands of hours).
Press the right button to increment by one or hold the button
to increment continuously. When the desired number is reached,
press the left button once to proceed to the next digit.
Repeat this process for all 5 digits.
2.6.6 Exiting Configuration Mode
The configuration mode can be exited in three ways:
1. Press and hold the left button for three seconds.
2. Leave buttons untouched for 30 seconds.
3. Press the left button after selecting the last (right) digit of the last
function available.
3.0 Operation
When the main power (9-60 VDC) is applied to V+ and V–, a
power-up sequence is initiated. All display segments are illuminated
for one second. The display is then turned off until the keyswitch
is activated.
3.1 Button Use During Normal Operation
3.1.1 Toggling Display Functions
Press the left button to sequentially toggle between the three numeric
gauge functions (time-of-day clock, maintenance hours, total hours).
The following procedures (3.1.2 and 3.1.3) can be done without V+ applied to
Setup Enable pin. Press and hold the left button on the front panel until the
entire display flashes and then release.
3.1.2 Setting/Changing the Time-of-Day Clock
See Section 2 .6.2.
3.1.3 Resetting the Maintenance Hour Meter
Press the left button until the maintenance hour meter function is
displayed (the wrench icon will be illuminated). Press and hold both the
right button and the left button until the display flashes and the
maintenance hour meter is reset to zero. This can be performed at any time,
independent of the actual maintenance status.
3.2 Auto-range
Curtis enGage® II will automatically recognize battery voltage based on the
status of the auto-range input pin.
3.3 Output and Warning LED
KEY: RMB = Right Most LCD Bar / LMB = Left Most LCD Bar
3.4 LCD Icons
Curtis enGage® II contains a number of icons to assist the user:
Hourglass Icon: Turned on (not blinking) to indicate that an hour meter is
displayed in the numeric display. Flashes to indicate hour meter accumulation.
Wrench Icon: Turned on (not blinking) to indicate that the maintenance hour
meter is displayed in the numeric display. Flashes when the maintenance
interval is reached.
Colon: Flashes to indicate that the time-of-day clock is being displayed in
the numeric display and that time is counting-up.
Decimal Point: To indicate 1/10 of an hour on the maintenance hour meter
Fuel or Battery Icon: Turned on (not flashing) depending on which function
the gauge is programmed to monitor. It flashes when a low condition is
detected.
Percent: Indicates remaining percentage of interval or level.
3.5 Resetting BDI
OCR—Open Circuit Reset: The BDI will reset when gauge is disconnected from
discharged battery and reconnected to a fully charged battery.
CTR—Charge Tracking Reset: Battery state-of-charge will be tracked by gauge
during charging period(s).
