3 SPECIFICATION FOR THE INPUT DEVICES
FILLING UP THE INSTALLATION KIT
The AC-0 controller needs some external parts in order to work. The following
devices complete the kit for the AC-0 installation.
3.1 Microswitches
- The microswitches must have a contact resistance lower than 0.1 Ω and a
leakage current lower than 100 µA.
- When full load connected, the voltage between the key switch contacts must
be lower than 0.1 V.
- The microswitches (if not otherwise noted) must connect or break a battery
voltage to the inputs pins.
3.2 Accelerator unit
The accelerator unit can consist of a potentiometer or an Hall effect device.
It should be in a 3-wire configuration. The potentiometer is supplied through
CNB#12 with about 12 Vdc.
CPOT (CNB#10) signal ranges is from 0 to 10 V.
Potentiometer value should be in the 0.5 - 10 kΩ range; generally, the load
should be in the 1.5 mA to 30 mA range. Faults can occur if it is outside this
range.
The standard connection for the potentiometer is the one in the Left side of
Figure 3–1 (potentiometer on one end at rest) in combination with a couple of
Travel demand switches. On request it is also possible the handling in the Right
side of Figure 3–1 (potentiometer in the middle at rest) in combination with at
least one Travel Demand switch. We strongly advice against the adoption of the
Right side configuration without travel demand switch at all, because of a safety
issue.
Figure 3–1
The Procedure for automatic potentiometer signal acquisition is carried out using
the Hand Set. This enables adjustment of the minimum and maximum useful
signal level (see paragraph 10.3 PROGRAM VACC function), in either direction.
