If the voltage is above the pre-set level, it enables the liftgate to work. The Liftgate Protector monitors battery level, and if it falls below the pre-set, it prevents activation of the liftgate and (if operating switch is active) activates an external alarm. Typical alarms would be a blinking light or buzzer. Once the switch is deactivated, an external override switch permits one-time use, so that liftgate can be stowed. Liftgate Protector prevents further use of the liftgate until battery level is restored. 5 When batteries are overdrawn, irreversible damage can be caused, and expensive batteries will have greatly reduced capacity or need Littelfuse Commercial Vehicle Products • 20 Old Colony Avenue, Boston, MA USA 02127-2467 210. 621.1845 • www.colehersee.com • www.littelfuse.com Littelfuse Commercial Vehicle Products to be replaced. Liftgate Protector prevents excess draw-down of batteries. Liftgate motors are dependent on supplied voltage. When voltage falls, they draw higher and higher current which can readily cause burned out motors. Liftgate protector prevents motor burnout. No hung-up liftgates. Even if battery is low, Liftgate Protector enables one-time override, so that liftgate can be stowed and vehicle is not immobilized. D-656 Rev A The FlexMod Family of Products Common FlexMod Applications TM The FlexModTM family is a series of small, robust solidstate modules with two inputs (one analog and one digital) and two solid state outputs (one 10A, one 200mA) that can be programmed to do almost any job. Standard units listed below are designed for specific types of applications, although they can be set to a wide range of parameters by dealers with programming units. TM Easy snap-in wiring with standard sealed connector Two outputs, two inputs Cole Hersee designed these units to solve problems in many industries. Here are a few of the thousands of potential applications. Contact us with your specific application requirements. Compact unit 3" x 4" x 1" Traffic Arrow Board Optional Relay In-Cab Radio 48610 Low Voltage Disconnect Monitors voltage. Preserves battery charge and protects battery banks by automatically disconnecting loads when battery voltage drops to a critical level. Unit 48610, unit & harness 48610-01, programmable unit 48710, programmable unit with harness 48710-01. See Hot Feed D-630 External Alarm Ultra-low standby current Battery Microrelay Sealed to IP67. Can be mounted anywhere FlexMod Dimensions 4.00 [101.6] 48541 & 48542 Voltage Sensing Relay & Timer Monitors voltage and time, and is available in two types: one load + pilot/alarm circuit; two loads. The unit monitors ignition status, shutting down non-critical loads when the cutoff voltage is reached, or at the set time after the ignition is turned off. Single output version 48541, unit & harness 48541-01, programmable unit 48741, programmable unit with harness 48741-01. Dual output version factory-set/programmable unit 48741, and this unit with harness 48741-01. See Hot Feed D-633 (single load VSRT), and this HotFeed (D-644) for Dual VSRT. Engineering Panel Lights 1.01 [25.8] 0.27 [6.9] Light Bar Radios 0.62 [15.7] Cordless Light Charger Computers 8-Pin sealed Deutsch connector Program the 48710 FlexMod LVD to combine low voltage warning and/or single circuit load management in one unit. A second 48710 FlexMod LVD can manage other loads, and if mounted close to the loads, will minimize wiring runs. Battery 2.70 [68.6] 1.31 [33.3] VSRT Battery Optional Relay Typical Application 3 Combined timer/voltage shutoff for police vehicles 48541 FlexMod VSRT combines two functions (time and voltage) in one small unit that opens up options for mounting in a small space, and simplifies wiring and other components. The FlexMod VSRT protects starting power with simultaneous sensing of time and voltage. Internal Lighting Dealer programming of units FlexMod is a highly versatile unit that can be programmed by dealers, to meet the customers’ specific applications. Parameters of time, voltage, and current limits are easy to customize, using straightforward on-screen options. Our programming unit connects your computer directly to a FlexMod, which can be programmed within minutes. The system has the advantage of accessing the FlexMod electronics via the integral connector. Unlike competitive products, this is a straightforward non- invasive process which does not compromise the waterproof integrity of the unit. Typical Application 2 NFPA 1901 Load Manager compliance for fire vehicles LVD LVD 3.30 [83.8] 48540 Smart Battery Isolator Controller Monitors voltage on two battery banks. Unit monitors two battery banks and controls one or more relays or contactors to make sure starting power is protected, by isolating the starting and auxiliary battery banks.

See Hot Feed D-632 Compartment Lights TM Radios & Computer Use the 48610 FlexMod LVD to protect starting power, and save fuel (and fines!) by eliminating idling. By connecting safety signboard (or other loads) to the LVD, the signboard can be safely run with the engine off, without the risk of a dead battery. By connecting the horn or external alarm to the alarm circuit, the vehicle operator will be warned of impending shutdown. Flashlight Charger Horn 48636 Lighting Timer Monitors time. Prevents the internal lights inside a trailer from being left on and draining the battery. Vehicle operator operates a handy momentary switch to turn lights on, giving safe and sufficient light within the cargo compartment. After 20 minutes the unit flashes the compartment lights to give the operator sufficient warning either to exit or re-set the switch.
