Note: 

When operating in this mode, the 

Er. 2

 error message displays at 

startup or after material changes. To clear the error code and 
silence the alarm, if installed, press the Clear key combination by 

pressing and holding both the 

 UP key and DOWN key 

together simultaneously.

 

 

•  enable a customer-supplied auxiliary proximity switch (

1

  ) 

This proximity switch is typically mounted low in the machine bin 
below the hopper loader, and is wired into the hopper loader as 
shown in Figure (14). When enabled in this mode, the hopper loader 
fills the machine bin below it, then stops operation. 

Operation does not resume until the auxiliary proximity switch 
senses that the material level has dropped below the proximity 
switch. The hopper loader then refills the machine bin. 

•  disable a customer-supplied proximity switch (

0

 ). 

Set this parameter to 

0

  if you aren’t using an auxiliary proximity 

switch or if you won’t be disabling an installed auxiliary proximity 
switch. 

 

8  SPI Communication Enable 

0 ) 

The SPI Communication Enable menu lets you: 

 

•  enable the SPI communication function (

1

  ) if the hopper loader 

has the SPI communication option installed and is on an SPI 
network 

•  disable the SPI communication function (

0

  ) if the SPI option is 

installed, but the hopper loader is not currently on an SPI network 

„

  Press the 

 START/STOP/SELECT/SET key to stop the hopper 

loader. 

 

For maintenance or for a long-term shutdown, unplug the unit from the power source and 
shut off the compressed air supply.
