1.10.1
Priority of control
The iL system can be controlled by a number of modules: the Pump Display Module (see
Section 1.11); an iL Interface Module (see Section 8.4.5); or the iL Single Pumpset Monitor (see
Section 8.4.7). Only one module can have control of the iL system at any one time. That is, once a
module has control of the iL system, control requests from another Module are denied.
To allow another Module to control the iL system:
•
The Module which currently has control must 'release' control (that is, you must send the
appropriate message on the network or press the appropriate button to release control).
•
Any Module which requires control must then 'take' control (that is, you must send the
appropriate message to the iL system or press the appropriate button to take control).
Note that when you first switch-on the electrical supply, no Module will initially have control of
the iL system. The Module which you want to control the iL system must take control as
described above.
