Switching on and Use of TV 401/301/21 NSF

To switch on the TV 401/301/21 NSF it is necessary to supply the
mains. The integrated controller automatically recognizes the
interlock and start signals presence and start up the pump.
The first pump start up is in "Soft Start" mode. When the start up
cycle is finished, the "Soft Start" mode automatically is disabled, and
the following start ups are without the "Soft Start" mode. To re-
enable the "Soft Start" mode it must be activated by the suitable
software command (see the paragraph "RS 232/485 COMMUNI-
CATION DESCRIPTION" in the appendix "Technical Information").
The green LED located on the TV 401/301/21 NSF base front panel
indicates with its flashing frequency the system operating conditions:
232/294
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.
