OPERATION
Control Options
77
The Anti-Jam feature can be used in submersible and grinding pump applications in locked impeller condi -
tions. When enabled, it works in Auto and Hand modes, and the VFD will provide automatic anti-jam func -
tion if a stall condition is detected.
•
If VFD trips or stops on Overload (OL), it will start the Anti-Jam cycle after a 10-second delay.
• The Anti-jam cycle provides five 6-second and half-speed starts, three in reverse and two in forward
direction with 2-second intervals. It starts in Reverse and then alternates Forward and Reverse starts.
• When the Anti-Jam cycle (5 starts) is completed and the 5-second timer expires, the VFD will start the
motor normally and try to run the pump. If VFD trips on OL again, it will start second Anti-jam cycle
after 10-second delay.
NOTE: If impeller is not freed during two Anti-Jam cycles, the VFD will trip on overload and will require
reset.
NOTE: The HLD function is disabled during Anti-Jam mode.
To enable the Clean Pump and/or Anti-Jam functions, set the following parameters:
Clean Pump Select [ADV2-55]: Set this parameter to the required cleaning function:
•
1_Clean Pump
: set to enable the Clean Pump feature.
• 2_Anti-Jam : set to enable the Anti-Jam feature.
•
3_Clean/Anti-Jam
: set to activate both features.
Clean Pump Timer [ADV2-56]: Set this parameter to desired interval in minutes for Clean Pump starts. The
timer will start at every VFD stop.
OCA Level [PROT-07] and OCN Level [PROT-08]: Set to desired stall level for Anti-Jam function.
Timers
IMPORTANT: If two or more timers are activated with different time settings, the timer with the greater
value will override other timers with a similar function.
Power On Run Delay
This timer provides run delay at VFD power-up with run command present to prevent multiple starts during
power surges.
Set the following parameter to activate this feature:
Power On Delay [ADV–28]: Range = 0 to 6000 sec. (Default = 10 sec). When set to 0 sec, it is disabled.
When set to a value greater than 0 and VFD is powered up in any HOA mode, the timer will start counting
and VFD start will be disabled until the timer expires.
Run Delay Timer (For Auto Mode)
This timer provides a delay at every VFD start when a run command is applied. The timer takes effect before
every VFD start by run command, auto-restarts, sleep wake-up, etc.
NOTE: FO (Fire Override) mode will disable this timer.
Set the following parameter to activate this feature:
Run Delay Timer [ADV–29]: Range = 0 to 6000 sec. (Default = 0 sec). When set to 0 sec, it is disabled.
When set to value greater than 0 and VFD receives a start command, wakes up, auto resets, or restarts after
a fault reset, the Start Delay timer will start counting. During timer counting, start is disabled and the VFD
cannot be started in Hand or Auto mode. Stop command, Sleep mode, or tripping on a fault will reset this
timer.
