Start Delay
This feature is designed to delay the pump from starting once a start command has been received. When a start signal is
received, the drive will delay starting by a set amount of time. A value greater than 0 activates this function. It will become
active on every start.
Examples:
1. A generator is used for the Power Supply for Backup when a power failure occurs. Once the generator starts it take a
few seconds for the power to stabilize. The PS220 may fault off during this unstable period.
2. Oil needs to circulate to the bearings of a pump before it can rotate. Once the start command is issued, a wired relay
could be configured and wired to start a circulation system first. The pump would then start after this delay has expired.
Parameter Name Value/Range Notes
74.04 START DELAY 0-9999 Seconds
0 [default]
This is the time in seconds the drive will delay starting the
pump once a start signal is received. This will work in
Local or Remote.
Starting & Stopping
Starting and Stopping the PumpSmart PS220 can be accomplished by many methods.
The default is the keypad pictured. If there is a solid green light on the keypad just above and to the left of the left arrow
key, you should be ready to run the drive. If it is red there is an active fault that will need to be investigated.
1. Local Control Start/Stop
When in LOCAL control the drive will run completely in manual mode and bypass all PumpSmart PS220 settings. It will
run in manual speed control and can only be started and stopped with the Red and Green Buttons. The reference running
speed can only be adjusted by the arrow up and down keys, or with the Options key.
When in REMOTE control all the PS220 Functionality is active.
To verify if the drive is in LOCAL or REMOTE, check the top left-hand corner of the keypad
→
display. The current mode,
either “Local” or “Remote” will be displayed. A diamond symbol will appear next to the word Local/Remote if the basic
start command is assigned to the keypad.
