Display information
■ Operation display
* Push the RETURN/RESET key to turn off the Alarm LED if it lights.
■ Total count display
Total number of pump shots will be shown if the DOWN key is pressed once. A push of the UP key calls back
the operation display.
Speed compensation (AUTO mode)
The LPC-1 controller reduces pump speed below the interlock speed (the fast alarm speed plus 10spm. See
page 55 for detail) when it rises to that rate or above.
* The LPC-1 normally switches the SV by the input from the proximity switches, but then during the speed compensation
the controller operates the SV independently of the proximity switches.
■ External input for speed compensation operation
In AUTO mode, input of the external signal (CN5 PIN5 dry running start/stop signal) from user PLC to the LPC-
1 controller can also start the speed compensation. Note teaching behaviour is automatically made right before
speed compensation.
* Teaching behaviour always functions once the pump speed has risen to the interlock speed or above before speed com-
pensation is started.
* Always input the dry running start/stop signal while the CN5 PIN1 START/STOP signal is inputted.

Regulator air pressure
If electropneumatic regulators instead
of normal regulators are used to the
operation with no feedback control, the
pressure value shown here will double
the actual starting pressure.
