5.1.1 Input connector description
E1 RV3 / QUICK I Input for 3rd speed reduction request. The request is
active when the pin is disconnected. To disconnect link
to +CH or adjust to level 9 the corresponding speed.
This pin can be programmed as input for rapid inversion
signal, the safety is active when pin is opened.
E2 RV2 / BACKING Input for 2nd speed reduction request. The request is
active when the pin is opened (low level) and discon-
nected if the pin is positive (high level) or the speed is
programmed to level 9.
If it is programmed as back request (backing), when
the pin is taken to a low level combined with a running
request, the running is activated with setted speed
through the parameter "CUTBACK 2" according to the
values defined at the point "BACKING SPEED" of the
adjustment chart and for a time with the parameter
"BACKING TIME". When this function is required it isn't
necessary to active the pin E4 (SEAT MICROSWITCH)
E3 RV1 Input for 1st speed reduction request which is active
when pin is opened.
The activation of this reduction is combined with an
intensity braking and programmable length (curve
braking)
It is possible to eliminate the braking in curve program-
ming curve time as 0.
E4 MSED / HANDLE Input for seat microswitch signal (delayed 2 sec.) if the
pin is taken to a high potential the running is active, the
delay isn't executed if the pin is programmed as
tiller-handle.
E5 MF Input for brake pedal microswitch when the pin is taken
high (+VB) during a release braking phase the braking
current is the one programmed at the parameter
"PEDAL BRAKING" plus a value that is proportional to
the accelerator signal and to the parameter
"BRAKING MODUL",
If the brake is pressed during the usual running the
current is reduced by 50% and the speed No. 2 reduc-
tion is activated.
E6 MI Input for backward request signal.
The request is active when the signal is high (+VB)
E7 MA Input for forward request signal.
The request is active when the signal is high (+VB)
E8 Same as pin E4 but active when signal is low
E9 Same as E8
H2B regenerative traction
