Resumen del manual
It complies with all the safety regulations as shipped from the factory. Installation and startup must be performed by skilled personnel. Failure to install and operate the unit in accordance with these instructions may result in damage or injury. If safe operation of the instrument can no longer be ensured, stop and secure it against accidental operation. If instrument failure or malfunction may cause personal injury or material damage, use additional safety measures such as limit switches, guards, etc. Read the Operating Instructions carefully before startup. ! ! Note the safety instructions marked with this warning symbol in this manual. TABLE OF CONTENTS Page 1. Model Encodement 2 2.

INSTALLATION The Model 833 Installation Kit includes a ! pre-assembled mating connector with 5” terminated wires. Ask for Curtis Part Number 15369002. The Model 833 fits into a dash-panel cutout measuring 21/16” (52 mm). Terminal Assignment (see diagram on page 13) Pin 8 = Battery + Pin 8 to battery + 7 Pin 5 = Battery – Connect to battery ground as close to battery ! as possible. Pin 2 = Keyswitch The keyswitch turns on and off the LED display of the battery discharge indicator. Monitoring of the battery continues when Pin 2 is turned off and the display is not lit. The hour meter display is unaffected by Pin 2, although it cannot accumulate more time as long as the keyswitch pin is not energized. The control input HRM (+) is enabled by the keyswitch. Pin 2 is connected to the vehicle’s keyswitch. Pins 1, 2, 6 & 7 = Hour Meter Control (+) In normal operation, Pin 1, 6 or 7 are connected when using normal hour meter function. It is possible to OR the hour meter between the three inputs so that it accumulates the total time either system is on. Hour meter control logic is detailed in Table 2. 8 Pin 3 = Relay (+) Pin 3 connects in series with the lift coil circuit (or the circuit to be switched at empty). For holding relay (J), Pin 3 must be electrically closer to battery + than Pin 4 Pin 4 = Relay (–) Pin 4 also connects in series with the circuit to be switched at empty. 9 Table 1.

If installing a fuse, use a 10A fuse wired with 1.5mm or equivalent wire. The voltage drop across the fuse, its holder, and connectors must be less than 1% of the nominal system voltage. Discharge Adjustments Table 3 lists the voltages per cell under load that correspond to an empty indication on the gauge (lockout point). Table 3.

OPERATION Display The Curtis Model 833 combines in one instrument a completely solid state LED battery state-of-charge indicator, an LCD hour meter, and lift lockout. Only when battery is properly charged is right most LED (1) lit. As battery’s state-of-charge decreases, successive LEDs light up, one at a time. 2nd from left LED flashes indicating “energy reserve” (70...
