Changing the device type
The process how to exchange one VariFuel2 type for another is described
below. However, the process can also be carried out correspondingly if you
change the device type. For example, you want to use the VariStep3 which
you used for a VariFuel2 gas mixer for a throttle.
Scenario:
You have replaced one VariFuel2 gas mixer with another
VariFuel2 type.
Problem:
After connecting the new VariFuel2 gas mixer, the stepper motor
driver performs a reference run. However, since this configuration still
contains data from the first gas mixer, it is possible that the VariFuel2 may
leave the traversing range and be mechanically damaged as a result, or
there is a risk that the VariFuel2 has to be readjusted.
Solution:
The following procedure will help to solve the problem:
1.
Separate the first VariFuel2 from the stepper motor driver.
2.
Connect the MICT to the stepper motor driver.
▸
The defective connection with the stepper motor causes an
operating error.
3.
Switch to manual mode.
4.
Acknowledge the error via the MICT (
Device -> Error Acknowledge
).
5.
Change the configuration to the new VariFuel2 type.
6.
Download the altered configuration to the device.
7.
Separate the stepper motor driver from the supply voltage.
8.
Connect the new VariFuel2 with the stepper motor driver.
9.
Reconnect the stepper motor driver to the supply voltage.
▸
A reference run will be performed. The new VariFuel2 is then ready
for operation.
Tip:
When you first configure the VariStep3 stepper motor driver with the
option
None
in the drop-down list
Device Type
no operating error is
triggered after the device has been separated from the stepper motor
driver. You can now reconfigure the stepper motor driver directly.
