3.1.5. EXPLANATION OF SETUP MENU 5 - FLOWMETER
SIGNAL
51 With this setting the type of flowmeter output is selected. The settings with
LP (low-pass) filter are used to apply a build-in noise reduction.
Selections "active pulse" offer a detection level of 50% of the supply
voltage.

3.1.6. EXPLANATION OF SETUP MENU 6 - CONTROL
Two open-collector outputs (Optional: mechanic relays or active outputs) are available to control
relays or small valves (max. 50VDC
– 300mA). It is advised to use relay one for pump-start and
relay two for the valve control.
DELAY TIME
61 This is the time between the moment of a start-signal and the moment before
relay 2 will be switched on. In the mean time, relay 1 will be switched to
control e.g. a pump. With time 0.0 seconds, this function is disabled.
BEGIN TIME
62 After the delay-time (61), relay 2 will be switched-on as well. and the
“begin-time” becomes valid. The unit has to receive about twice the
number of pulses as programmed with setting 26, before “start-up time”
(setup 63) becomes valid.
If not enough pulses have been received within this time, the delivery will
be cancelled. With time 0.0 seconds, this function is disabled.
START-UP TIME
63 Now, the start-up time allows the system to become operational without
having a low-flow rate alarm. After this time, the system will become full
operational. With time 0.0 seconds, this function is disabled.
NO PULSE TIME
64 As soon as the unit is full operational, the flow can be monitored. The
F133-P will switch-off relay 1 and 2 (or relay 2 only: see setting 65/66) as
soon as during X-seconds no pulses have been received from the
flowmeter. In most cases, this is “end of process” (see 65).
With time 0.0 seconds, this function is disabled.
PAUSE
65
With this function, a “pause-function” can be enabled: if during the
process “stop” will be pressed, or the process is interrupted for another
reason like “no pulse time”, “flow rate alarm” or with the “status input”, the
batch will be stopped but can be resumed. If the unit comes in “PAUSE”,
relay 2 will be switched-off but relay 1 (pump control) remains energized.
Applications where this function is useful is delivery of sub-batches for
example where you want to have one “overall” total.
RESTART TIME
66 Following setup 65, the F133-P allows the Operator to restart a delivery
within X-seconds. If this does not happen within this time, the delivery will
be finished completely. With time 0.0 seconds, this function is disabled.
