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 ConfiguringYour 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.

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 slid-
ing 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.
