Solution Description
CURTIS 1243 Generation two MultiMode™ controllers are individually thrilled motor speed controllers made for use in a variety of little industrial automobiles and in substance handling gear. These programmable controllers are simple to install, effective, and value successful, although giving a lot more attributes than the unique 1243.
The 1243 GEN2 MultiMode™ controller offers sleek exact handle of motor pace and torque. A total-bridge field manage stage is merged with a fifty percent-bridge armature electrical power stage to give sound point out motor reversing and full regenerative braking CZPT added relays or contactors. The controller’s rugged IP53 housing and packaging are constructed to stand up to shock and vibration. Condition-of-the-art surface mount logic board fabrication makes the 1243GEN2 controller even a lot more trustworthy than the authentic 1243. The 1243GEN2 is fully programmable through the CURTIS Product 1313-4331 Handheld Programmer or 1314 Personal computer Programming Station. In addition to configuration overall flexibility, the programmer provides diagnostic and take a look at capability.

Features Consist of:
Interlock braking with load sensor to satisfy required braking distance CZPT needless severe braking at gentle masses
Upkeep monitor responds to preset vehicle running hours and generate hours as programmed by the OEM
Two hourmeters – whole KSI-on hours and traction hours – and the linked routine maintenance timers are developed into the controller
BDI calculations done within controller
Estimates motor temperature dependent on discipline resistance and cuts back again maximum pace if the motor is overheated
Diagnostic checks for subject open up and field shorted faults
Supports PWM electromagnetic brake with maximum steady present of two amps
Supports Type 4 throttle
Active precharge of controller capacitor lender extends life of primary contactor
Compatibility with CURTIS 1313-4331 Handheld Programmer or 1314 Personal computer Programming Station for quick and straightforward tests, diagnostics, and parameter adjustment
MultiMode™ makes it possible for four person-selectable automobile working modes
Constant armature current control, reducing arcing and brush wear
Comprehensive diagnostics by means of the handheld programmer, the created-in Position LED, and the optional 840 Spyglass display
Two fault outputs provide diagnostics to remotely mounted shows
Regenerative braking makes it possible for shorter halting distances, boosts battery charge, and reduces motor heating
Computerized braking when throttle is decreased gives a compression braking truly feel and boosts protection
Brake/Travel Interlock fulfills ISO halting distance demands
Ramp restraint function gives computerized digital braking that restricts automobile motion even though in neutral
Fulfills EEC fault detect needs
CZPT cutback of motor travel current during overtemperature or undervoltage
CZPT cutback of regenerative braking existing in the course of overvoltage
Large pedal disable (HPD) and static return to off (SRO) interlocks prevent car runaway at startup
Internal and external watchdog circuits make certain suitable software program procedure
Entirely guarded inputs and limited-circuit safeguarded output drivers.
