Tester: Functions Descriptions - Zapi SEM1 User Manual

14 HIGH FIELD CUR., NO FIELD CUR.
Problem in the FIELD current. Possible causes:
a. Failure of the current trasducer.
b. Field cables not connected.
c. Failure of the field power unit.
Some of the most importantly input/output signals are tested or measured in real time
(only stand-by status) and it is possible to read them through the menu TESTER of the
console.
1) BATTERY VOLTAGE: is the value of the battery voltage, measured on the "key
input".
2) MOTOR VOLTAGE: voltage across the motor's armature.
3) MOTOR CURRENT: armature current.
4) FIELD CURRENT: field current.
5) TEMPERATURE: temperature of the aluminium coding plate, close to the power
Mosfets.
6) ACCELERATOR: voltage measured on the CPOT (wiper of the potentiometer). On
the left of the display there is the voltage value, instead, on the right the percentage
of the stroke.
7) FORWARD SWITCH: status of the digital input corresponding to the forward direc-
tion microswitch (MA: pin A9).
ON / +VB = active, closed microswitch.
OFF / GND = not active, open microswitch.
8) BACKWARD SWITCH: status of the digital input corresponding to the backward
direction microswitch (MI: pin A10).
ON / +VB = active, closed microswitch.
OFF / GND = not active, open microswitch.
9) CUTBACK SWITCH 1: status of the digital input corresponding to the speed reduc-
tion microswitch n° 1 (RV1: pin A8).
10) CUTBACK SWITCH 2: status of the digital input corresponding to the speed reduc-
tion microswitch n° 1 (RV2: pin E2).
11) QUICK INVERSION: status of the digital input corresponding to the belly switch (IR:
pin A12).
ON / +VB = active, closed microswitch.
OFF / GND = not active, open microswitch.
12) HANDLE / SEAT SWITCH: status of digital input corresponding to the microswitch
tiller / seat (MT / MSED: pin A11).
ON / +VB = active, closed microswitch.
OFF / GND = not active, open microswitch.
