3 — PROGRAMMABLE PARAMETERS: Brake and Horn Parameters
BRAKE MENU
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Delay 0–1 sec Sets the length of delay between when zero speed is commanded and the
electromagnetic brake is engaged.
Fault Check On/Off Enables/disables the fault detection on the EM brake.
Hold Voltage 10–24 V A high initial voltage is applied to the brake coil when the brake is first
released. After approximately 1 second, this peak voltage drops to the
programmed Hold Voltage. The parameter should be set high enough to
hold the brake released under all the shock and vibration conditions the
vehicle will be subjected to.
Brake Light On/Off When set to On, the horn output (J1 Pin 3) will act as a brake light driver.
The brake light must be driven by a relay, as shown in Figure 8.
The brake light will be turned on when the throttle is returned to neutral
and will remain on for about 2 seconds after the EM brake is engaged.
When the horn output is used as a brake light driver, Fault Beep (see
Horn menu) should be programmed Off.
When Brake Light is set to Off, the horn output acts as a horn driver.

HORN MENU
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Fault Beep On/Off When programmed On, the horn will be used to provide audible fault
codes whenever faults are present. These are the same fault codes that
are flashed by the status LED. If a fault should occur while the vehicle is
driving in reverse with the reverse beep active, the fault signal will take
precedence. If this audible fault alarm is not wanted, set Fault Beep to Off.
Reverse Beep On/Off When programmed On, the horn will sound whenever the vehicle is being
driven in reverse. On vehicles with reverse switches, the horn will sound
when the reverse switch is activated.
Beep Constant On/Off Sets the reverse beep to be a constant tone (when programmed On)
or a 1Hz pulse (when programmed Off).
