Switching on and Use of TV 903 Pumping System
To switch on the TV 903 Pumping System it is necessary to supply a voltage of
48 Vdc. The integrated controller automatically recognizes the interlock and
start signals presence and start up the pump.
“Soft Start” mode is provided to start the pump after a protracted stop. This
allows a better grease distribution in the bearings. To enable the “Soft Start”
mode it must be activated by the suitable software or Remote I/O command
(see the paragraphs “INTERCONNECTIONS” and “RS 232/485
COMMUNICATION DESCRIPTION” in the appendix “Technical Information”).
The green LED located on the TV 903 Pumping System base front panel
indicates with its flashing frequency the system operating conditions:
with no flashing: the pump is normally rotating;
slowly flashing (period of about 400 ms): the system is in ramp, or in
braking, or in Stop, or in “Waiting for interlock” status;
fast flashing (period of about 200 ms): error condition.
TV 903 Pumping System Switching off
To switch off the TV 903 Pumping System it is necessary to remove the mains.
The integrated controller immediately stops the pump.
WARNING! The TV903 Pumping System Power Supply (969-6501) must be powered with
3-wire power cord (see orderable parts table) and plug (internationally
approved) for user's safety. Use this power cord and plug in conjunction with
a properly grounded power socket to avoid electrical shock and to satisfy CE
requirements. High voltage developed in the controller can cause severe
injury or death. Before servicing the unit, disconnect the input power cable.
