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.
Maintenance interval
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 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.
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.
10
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.
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 key switch is activated.
Setting the Maintenance Interval
Apply V+ (9 to 60VDC to the set up enable pin (2).
Press and hold the Left button on the front panel until
the display flashes and then release. The display will
flash the two "Hours" digits , Press the left button
once. The display will flash the two "Minutes" digits ,
Press the left button once. The display will flash the
maintenance 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. , Press
the left button once to exit.
Toggling Display Functions
Press the left button to sequentially toggle between the
two numeric gauge functions (time-of-day clock,
maintenance hours).
Setting the Time-of-Day Clock
This 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.
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.
Resetting the Maintenance Hour
Meter
This can be done without V+ applied to Setup Enable
pin. 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 the preset
maintenance period. Release the right button first. This
reset function can be performed at any time,
independent of the actual maintenance status.

Installation
Caution!
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.
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.
Curtis enGage™ II mates with 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
17631800-01) with crimp-connect terminated wires
(approx. 5 inches in length) is also available.
