40-Series Manual, Rev. B
The powerbase has three Multi-Function Inputs, which can be used to create a
very flexible array of seat adjustment and drive speed limiting functions.
The speed limits imposed by the Multi-Function inputs act like speed
modes; they cause an interpolation between each of the min and max parameter
pairs in the active profile (Profile 1 or 2). Note that the final speed limit of the
chair is always the lowest of all the applicable limits.
Each of the three Multi-Function inputs has its own programming menu.
Multi-Function Input 1 can be used to inhibit the actuators or to set a speed
limit, with either a high (B+) or a low (B-) input. It can also be used to provide
a variable speed limit based on the position of a potentiometer, or to accom
-
modate a high-side or low-side onboard charger. Multi-Function Input 1 is at
Pin 5 on the 14-pin connector; see Figure 6, page 9.
5 — PROGRAMMABLE PARAMETERS: Multi-Function Input 1 Parameters
MULTI-FUNCTION INPUT 1 MENU
PARAMETER RANGE DESCRIPTION
Off / InbL / InbH / Spd 0–3 0 = Multi-Function Input 1 ignored.
1 = Inhibit drive or actuators when input is low.
2 = Inhibit drive or actuators when input is high.
3 = Speed limit varies with input voltage.
Charger Inhibit On/Off Enables Input 1 to be used with an on-board charger. The charger
pulls the inhibit active during charging, which will inhibit drive, light
the charger and battery icons in the handcontrol display, and engage
the EM brake.
Halt Act 1 Dir- On/Off Actuator 1 will be halted in the negative direction.
Halt Act 1 Dir+ On/Off Actuator 1 will be halted in the positive direction.
Halt Act 2 Dir- On/Off Actuator 2 will be halted in the negative direction.
Halt Act 2 Dir+ On/Off Actuator 2 will be halted in the positive direction.
Speed Limit Low 0–100 % Sets the speed limit when the input is low or the potentiometer
wiper is fully to B-.
Speed Limit High 0–100 % Sets the speed limit when the input is high or the potentiometer
wiper is at 100K to B-.
