Table 4-2 Set Options - Continued Parameter Factory Setting Description AUX OUTPUT #1 BRAKE This option handles output CNA#3 (Table 4-5). It can be used as: • BRAKE: CNA#3 (Table 4-5) drives an electromechanical Brake. • HYDROCOMNT: CNA#3 (Table 4-5) drives the contractor for a hydraulic steering function when the direction input or brake pedal input are active or a movement of the truck is detected.

Parameter Factory Setting Description AUX VOLTAGE #1 100% This option specifies the percentage of the keyswitch controlled voltage to be applied to the loads on CNA#1 (Table 4-5) (main contactor coil) and CNA#3 (Table 4-5) (electromechanical brake). The voltage modulation is set with a PWM at 1 kHz frequency. After an initial delay of about 1 sec in which the entire keyswitch controlled voltage is applied to the loads, the PWM reduces the voltage at the loads down to the specified percentage.
4-2.4.2. Adjustments To change an adjustment proceed as follows and refer Table 4-3: Connect the Zapi Handset, refer to paragraph 4-2.1. Press the ROLL up button (1, Figure 4-3) and the SET up button (5) at the same time to enter the CONFIG MENU.
Parameter Factory Setting Description THROTTLE X POINT This parameter together with the THROTTLE Y POINT, changes the characteristic of the accelerator input curve: when the acceler- ator is de-pressed to X point percent, the corresponding truck speed is Y point percent of the Maximum truck speed. The rela- tionship between the accelerator position and the truck speed is linear between the THROTTLE 0 ZONE and the X point and also between the X point and the maximum accelerator position but...

Table 4-4 Parameter Adjustments - Continued Parameter Factory Setting Description CUTBACK SPEED 100% Typically from 10% to 100%. It determines the percentage of the max speed applied when the cutback switch 1 (SR#1 on CNA#15 (Table 4-5) is active. When set to 100% the speed reduction is ineffective.
