3.2Operating parameters

The control system allows the following operating parameter settings (realization see item 4). The resulting behaviours are described in the chapter operating conditions. The values in brackets are the standard values after system reset (see item 4.4.4).

LIM	function:	Permeate limit value used to switch the unit off in
		case limit is exceeded or if a DISPOSAL process
		is to be finished. If this value is exceeded during
		PRODUCTION, RINSE or CONCENTRATE
		DISPLACEMENT/FLUSH for the time defined for
		t-delay LIM, an ALARM MESSAGE will be
		activated.
	right of access:	user/technician
	possible setting: meas. range 0.5-50µS/cm (40 µS/cm)
		Attention: the set value must be above aaLIM
aaLIM	function:	Permeate limit value activating an ALARM
		MESSAGE in the display and on/off of the
		malfunction LED if this value is exceeded for the
		time defined for t-delay aaLIM
	right of access:	user/technician
	possible setting:	0.5-50µS/cm (10 µS/cm)
		Attention: the set value must be lower than LIM
t-delay LIM	function:	Time delay for wrong permeate limit value
		(see above)
	right of access:	technician
	possible setting:	0-99 min (1 min)
t-delay aaLIM	function:	Time delay for advance alarm in case of wrong
		permeate limit value (see above)
	right of access:	technician
	possible setting:	0-99 min (5 min)
t-delay lack of pressure	function:	Time delay to release PRESSURE FAILURE if
		PRESSURE SWITCH is inactive.
	right of access:	technician
	possible setting:	0-99s (1s)

t-delay at start	function:	Period of time of permanent pressure at start of
		operation after opening of the inlet valve before
		the pumps begin to work.
	right of access:	technician
	possible setting:	0-9.9s (0.5s)
t-pressure available	function:	Period of time until PRESURE FAILURE is
		released if pumps do not start after opening of
		inlet valve.
	right of access:	technician
	possible setting:	0-99s (5s)
t rinse	function:	Duration of a DISCONTINUOUS RINSE.
	right of access:	technician
	possible setting:	0-99 min (5s)
