Control Feature Descriptions

Regenerative Barking –

1. Control keeps vehicle from over speeding and regulates speed to value set by function 20 in Table 1 or the value set by table 2. This function is engaged when start switch is closed and speed reaches value set by function 20 or the value set by table 2.
2. Control slows vehicle down to approximately 10 MPH when start switch is opened.

Zero Speed Detection – Control prevents vehicle from rolling away once control see’s zero speed and no further inputs are received at the control. This function retarding torque is limited by max current allowed as set by function 5.

Reverse Buzzer Driver –

1. Turns customer supplied buzzer on when control see’s reverse signal.
2. Buzzer is also turned on and off when zero speed detect is initiated.
3. Buzzer current not to exceed 50mA.

SRO – Static Return to Off –

1. Vehicle will not run if the key is turned on with accelerator switch closed.
2. Vehicle speed is limited to Pedal up speed limit if the key is opened when the accelerator pedal is full on.

Plugging – Control provides retarding torque when a direction switch occurs. Retarding torque is limited by function 5 setting table 1

Reverse Speed Limit – Control limits motor volts to a valued specified by function 12, table 1, when control see’s reverse switch closed. Function 3, table 1, is doubled in reverse.

Reverse Battery Protection – If battery cables are hooked up backwards control will not allow line contactor to close.

Throttle wire Protection – Control will not run if +5v or wiper negative connection is open. 4V or greater at start switch closure.

Reverse Motor Protection – If (I) A and (I) F lead is switched control will not be damaged.

Stall Protection – If armature current is 145A or greater when speed is 1 MPH or less for 4 seconds, armature % on-time will be reduced by 8%. The timer is then reset to reactivate the stall protection feature.

Validation Testing

Thermal Shock – One control was soaked for one hour at -40oC then transitioned to 105oC within 5 seconds and soaked for 1 hour, to complete one cycle. Test preformed 100 cycles and control card operated properly after test.

Environmental Protection – TESTED TO IP53

Vibration – One control has been subjected to the Navy Manufacturing screening program (NAVMAT – P9492) vibration test. Random vibration from 20Hz to 2000Hz for 5 minutes in each plane (X,Y,Z). The Magnitude is 20 G rms. Control properly operated after test.

Shock – One control was subjected to 3 pulses of 20G in each of the 3 major axis. No physical damage occurred and control properly operated after test.

Power Cycle – One control was operated at full current rating (50% on time) for 10 seconds and off for 40 seconds. Control completed 100,000 cycles.
