How to reset PROLiNK PRO2000LD password if lost?
If password access is not available for your PROLiNK UPS because the password is lost or forgotten, contact a repair center for resetting the new password.
Why PROLiNK PRO2000LD UPS does not switch to battery mode or backup time is short?
If your PROLiNK UPS isn't switching to battery mode during a power outage, or the backup time is less than expected, check these potential causes: * Ensure the batteries (48VDC nominal) are properly connected. * Verify the battery circuit breaker is turned on. * The battery may not be fully charged; recharge it and then test the discharge time. * The battery might be dead, in which case you should replace it with new batteries. * There may be a UPS fault; if so, return to a repair center.
What to do if PROLiNK PRO2000LD has no output?
If there is no output from your PROLiNK UPS, check the following: * Ensure that both the AC input and output circuit breakers are turned on. * Verify that there is line power input and turn on the AC input breaker if it's off. * If the red LED is lit solid on the front panel, read the fault event in the LCD display, manually restart the UPS, and contact the factory if the fault persists.
Why PROLiNK UPS batteries will not charge?
If the batteries of your PROLiNK UPS are not charging: * Check if the battery cable is firmly connected and the battery connection is correct. Any connection error, loose or open connection will cause a circuit to open. * Verify that the proper battery voltage is detected on the battery connector of the UPS. * Ensure that the battery breaker is closed. * If the battery is bad, replace it. Also, ensure that you are only using the factory-supplied temperature probe reading approximately 15,000 OHMS @ 25°C (77°F), if the temperature probe is connected.
What to do if PROLiNK PRO2000LD does not return to Line mode?
If your PROLiNK UPS doesn't switch back to Line mode, make sure that: * The power cord from “UPS IN” on PTS is properly connected to the AC input terminal blocks on the UPS. * The “UPS INPUT” circuit breaker on PTS is closed. * The AC input circuit breaker on the UPS is closed. * Line input is present.
How to fix no output from PROLiNK UPS PTS?
If there is no output available from the PTS of your PROLiNK UPS, consider the following possible causes: * The external AC circuit breaker may be open, so close it. * Line AC power may not be available; check if utility power is available with an AC voltmeter and contact the Utility Company if needed. * There may be a wiring error on the PTS terminal blocks; correct the wirings. * There may be a PTS fault; if utility power voltage is present at AC IN “L” and “N” on the PTS terminal blocks, replace the PTS.
What to do if PROLiNK PRO2000LD UPS PTS doesn't transfer to battery mode?
If your PROLiNK UPS's PTS is not transferring to battery mode, check the following: * Verify if the power cord from “UPS OUT” on PTS is properly connected to the AC output terminal blocks on the UPS. * Ensure the “UPS INPUT” circuit breaker on PTS is not open; reset the breaker if needed. * Confirm that the black and red control wires from PTS are connected to the PTS control connector of the UPS. * If 48VDC signal is not available at the PTS control connector on the UPS, replace the UPS. * There may be a PTS fault; if so, replace the PTS.
Why is the output LED off on my PROLiNK UPS?
If the output LED on your PROLiNK UPS is off: * Ensure that line power or battery power is available by applying qualified input power and making sure the battery breaker is closed. * There may be a UPS fault; if so, return it to a repair center.
