1 ELECTRONIC SWITCHES Single Level Speed Swit ch 12V R490 l 211V NA Speed switch will trip at preset rpm to control engine function or other control circuitry. Relay out puts can also be used to switch external circ uit on or off at trip point. When ordering, specif y sensor or ignition input. latched or auto -reset r elay. and the desired switch point. Adj usta ble Single Level Speed Switch 12V R490l A 2l1V R490lA 24VDC R4901A is field adjustable and desig ned to be used as an over rev alarm or road speed alarm. When sett ing is exceeded, a warning device or shutdown is activated. This unit accepts signals from ISSPRO magnetic pickup or signal generator. Set point is adjustable from 100 to 5,000 her t z. R4901A is available in unlatched (auto-reset) version only. When t he set point is exceeded, t he relay will remain tripped unti l the sig nal fa lls bel ow the set point. when it will reset. Use R4901 factory preset to yo ur specifications fo r latched appli cations. R4901A is not compatible with ignition inputs. Dual Level Speed Switch R V R VDC R4902 is like R4901A except it has two switch points. one upper and one lower. When ordering, specify t he two switch points. sensor or ignition input. lat ched or auto rese t r elay. Single Lev el Temperat ur e Switch R V R VDC R6327 is designed to activate a warn ing when a predetermined exhaust temperature is reached. When ord er ing. specify ty pej or K thermocouple and temperature at which you wan t the device t o switch. Dual Level Temperature Swit ch R V R V DC R6326 Gives a two step warning when predetermined exhaust temperatures ar e reached. When the first swit ch point is reached. an initial warning signal is activated. When the second t emper atur e switch point is rea ched, additional warnings or systems are activated. Alarm points must be specified for factory set ting.

When engine ignit ion turned off. t he R4130 idles until a safe exhaust temperature is rea ched, th en automatically shu ts down the engine. By shutting down in a cool condit ion, deposits are r educed and tu rbo life is incr eased. Stand ard shutdown is F. For installation. the existing pyrometer system can be used or order lead wire R660 and a t ype K thermocouple.
