9.7.3 DLC, float-switch-controlled option
The control panel supports two different modes of operation based on selected parameter settings. See section 9.9 Adjustable
parameters for information on how to change the mode of operation and other adjustable parameters.
Your control panel can perform the functions listed below. Depending on the application, some functions may be omitted or combined.
* To determine a pump seal failure, overtemperature or overload failure trip, open the dead-front inner door and look for the following
relay conditions:
Overload relay: When the overload relay trips, the trip indicator is present on the device. The overload relay can be reset by pressing
the blue reset button. The overload relay can be switched to manual or automatic resetting.
K02: This relay is active when the overtemperature sensor in the pump has tripped.
K03: This relay is active when the seal-failure sensor in the pump has tripped.
K04: This relay is active when the overtemperature sensor in the pump has tripped.
K05: This relay is active when the seal-failure sensor in the pump has tripped.
High Level Alarm
• This float switch activates the alarm indication on the screen and the audible alarm when lifted for
longer than the high-level alarm delay.
• Press the Push-to-Silence button on the side of the control panel to silence the audible alarm.
• The alarm indication on the screen will remain on until the float switch is lowered, and the audible alarm
will reactivate in 12 hours if the alarm condition is not corrected.
Lag Pump On
• This float switch starts the lag (standby) pump when lifted (both pumps will be on).
• Both pumps will run until the pump(s) off float switch (if used) is lowered.
Lead Pump On
• This float switch starts the lead (duty) pump when lifted.
• The pump will run for the duration of the minimum run time or until the pump(s) off float switch (if used)
is lowered.
Pump(s) Off • This float switch stops the pump(s) when lowered if the minimum run time has elapsed.
Pump Fault*
• The pump failure is activated when the pump overtemperature sensor, seal failure sensor, or overload
relay has tripped.
• A pump failure will activate the alarm indication on the screen, the audible alarm, and an alarm
message on the user's screen.
• Press the Push-to-Silence button on the side of the control panel to silence the audible alarm.
