Pulse Flowmeter Setup; Ramps - Grundfos TPE 1000 Series Installation And Operating Instructions Manual

"Detection delay"
You can set a detection delay which ensures that the
monitored parameter stays above or below a set limit
in a set time before the function is activated.
"Resetting delay"
The resetting delay is the time from which the
measured parameter differs from the set limit
including the set hysteresis band and until the
function is reset.
Example
The function is to monitor the outlet pressure of a
pump. If the pressure is below 5 bar for more than 5
seconds, a warning must be given. If the outlet
pressure is above 7 bar for more than 8 seconds, you
must reset the warning.

You can connect an external pulse flowmeter to one
of the digital inputs in order to register the actual and
accumulated flows. Based on this, you can also
calculate the specific energy.
To enable a pulse flowmeter, set one of the digital-
input functions to Accumulated flow and set the
pumped volume per pulse. See section "Digital
inputs".

The ramps determine how quickly the motor can
accelerate and decelerate, respectively, during start-
stop or setpoint changes.
You can set the following:
• acceleration time, 0.1 to 300 seconds
• deceleration time, 0.1 to 300 seconds.
The times apply to the acceleration from 0 rpm to
fixed maximum speed and the deceleration from fixed
maximum speed to 0 rpm.
At short deceleration times, the deceleration of the
motor may depend on load and inertia as there is no
possibility of actively braking the motor.
If the power supply is switched off, the deceleration of
the motor only depends on load and inertia.
