Vacon 100 flow Applications Manual

P3.21.3.1 PRIMING FUNCTION (ID 1677)
Use this parameter to enable the Priming pump function.
A priming pump is a smaller pump that primes the inlet of the main pump to prevent the
suction of air. The priming pump function controls a priming pump with a relay output signal.
P3.21.3.2 PRIMING TIME (ID 1678)
Use this parameter to set the time that the priming pump operates before the main pump
starts.
10.21.4 ANTI-BLOCKING FUNCTION
The Anti-blocking function makes the pump not to get blocked if the pump is stopped in the
Sleep mode for a long time. The pump starts at intervals, while it is in the Sleep mode. You
can make a configuration of the interval, runtime and speed for the anti-blocking.
P3.21.4.1 ANTI-BLOCKING INTERVAL (ID 1696)
Use this parameter to set the interval for the Anti-blocking function.
This parameter gives the time after which the pump starts at the specified speed (P3.21.4.3
Anti-blocking Frequency) and for the specified quantity time (P3.21.4.2 Anti-blocking
Runtime).
The Anti-blocking function can be used in the Single drive and the Multidrive systems only
when the pump is in the sleep mode, or in the standby mode (Multidrive system).
The Anti-blocking function is enabled when the value of this parameter is more than 0 and
disabled when the value is 0.
P3.21.4.2 ANTI-BLOCKING RUNTIME (ID 1697)
Use this parameter to set the time that the pump operates at the set speed when the Anti-
blocking function is activated.
P3.21.4.3 ANTI-BLOCKING FREQUENCY (ID 1504)
Use this parameter to set the frequency reference of the drive that is used when the anti-
blocking function is activated.
10.21.5 FROST PROTECTION
Use the Frost protection function to protect the pump from frost damages. If the pump is in
sleep mode and the temperature that is measured in the pump goes below the set protection
temperature, operate the pump at a constant frequency (that is set in P3.13.10.6 Frost
Protection Frequency). To use the function, you must install a temperature transducer or a
temperature sensor on the pump covering or on the pipe line near the pump.
P3.21.5.1 FROST PROTECTION (ID 1704)
Use this parameter to enable the Frost Protection function.
If the measured temperature of the pump goes below the set level and the drive is in sleep
state, the frost protection makes the pump start and operate at a constant frequency.
