Priority of control
The pumping system can be controlled by one of a number of modules: the front control panel (refer to
Pump Display Terminal (PDT), the Edwards System Controller or by the tool through the MicroTIM or one of the serial
interfaces. Only one of these can have control of the system at any one time. That is, once one of these has control
of the system, control requests from the others are denied.
The PDT indicates what is in control. LEDs provided on the rear panel, front panel or PDT illuminate to indicate ‘in
control’.
Note:
The pump as supplied can only be controlled using the front panel. The PDT, System Controller and the
MicroTim are all accessories. Refer to
.
1.5
Green Mode
The Green Mode function reduces utility consumption of the system while on stand-by. The Green Mode functionality
is controlled via a PDT accessory or the tool via a MicroTIM accessory. Refer to
. Contact Edwards for
advice on application and activation.
Note:
This mode of operation can only be activated 20 minutes after pump start in order to allow for the pump
to warm up.
