Priority of control

The iXL120 system can be controlled by one of a number of sources: the front control panel (refer to
Pump Display Terminal (PDT) accessory or from the tool via the MicroTIM. Only one of these can have control of the
iXL120 system at any one time. That is, once one of these has control of the iXL120 system, control requests from
the others are denied until control is released by the first.
An LED is provided on the front panel, which illuminates to indicate that the pump is 'in control'. An LED is provided
on the rear panel which illuminates to indicate that the tool is 'in control'. The PDT accessory can identify which
source is 'in control' and also has an LED to indicate if the PDT itself is 'in control'.
