TNV Application Manual
To connect the accelerator position sensor input (APS: E35) and the backup analog sensor input (REAN:
E7) to the foot pedal (flag setting: 2 - 4), APP-IP2: E14 and APP-IP7: E13 must be configured to enable
reception of signals from the foot pedal switch. In addition, APP-IP2: E14 and APP-IP7: E13 must be
configured to enable connection with an NO switch and NC switch respectively. (Set APP-IP2 to NO and
APP-IP7 to NC. See
Table 2-15 . When the flag is set to 2, APP-IP2 and APP-IP7 must be set to NO and NC
respectively. When the flag is set to 3, APP-IP2 must be set to NO. When the flag is set to 4, APP-IP7 must
be set to NC).
Figure 2-33 shows the foot pedal operation and engine speed. When the flag is set to 2, the input voltage at
terminal APS or REAN is effective only when APP-IP2: NO is low and APP-IP7: NC is high. Otherwise, the
engine runs at low idling speed.
When the flag is set to 3, the input voltage at terminal APS or REAN is effective only when APP-IP2: NO is
low. Otherwise, the engine runs at low idling speed.
When the flag is set to 4, the input voltage at terminal APS or REAN is effective only when APP-IP7: NC is
high. Otherwise, the engine runs at low idling speed.
When two foot pedals are used, APS: E35 and REAN: E37 must be flagged to 3 and 4 (or vice versa)
respectively.
