DESCRIPTION
Type
0–3
The 1212S controller can accept inputs from voltage throttles and from
resistive throttles. Set the throttle type parameter to match the throttle used in
your application.
Voltage throttles
0 = single-ended; neutral when wiper ≤Neutral Deadband setting
1 = inverted single-ended; neutral when wiper ≥Throttle Max setting
Resistive throttles
2 = single-ended; neutral when wiper is at Pot Low side
3 = inverted single-ended; neutral when wiper is at Pot High side.
PotHigh
3.0 – 5.0 V
Sets the maximum voltage for voltage throttles (Types 0, 1).
(For resistive throttles, PotHigh is determined by the throttle itself.)
PotLow
0.0 – 2.0 V
Sets the minimum voltage for voltage throttles (Types 0, 1).
(For resistive throttles, PotLow is determined by the throttle itself.)
Neutral Deadband
5 – 30 %
Sets how far from neutral the throttle must move to begin vehicle movement
and release the brakes. This parameter allows the neutral deadband to be
defined wide enough to ensure the controller goes into neutral when the
throttle is released.
V
vnb
= (DB%) (PotRange)
Voltage throttles
PotRange = (PotHigh – PotLow)
Resistive throttles
PotRange = 5V – 2*PotLow
Guidelines for adjusting this parameter are provided in Section 5.
Throttle Max
40 – 100 %
Sets how far from neutral the throttle must move to request 100% input.
V
max
= (Max%) (PotRange)
Voltage throttles
PotRange = (PotHigh – PotLow)
Resistive throttles
PotRange = 5V – 2*PotLow
Guidelines for adjusting this parameter are provided in Section 5.
HPD
On, Off
When programmed On, the 1212S inhibits vehicle drive if a throttle command
outside the neutral deadband is issued when the interlock switch is turned on.
Drive will continue to be inhibited until the throttle is returned to within the
neutral deadband. If the HPD fault is not cleared within 10 seconds,
a wiring fault is declared and a power cycle is required.
