Sets the response of the pump to the low level float switch as either low level alert or alarm. Level Sensor Type 0.5 to 4.5 V Recommended setting is 0.5-4.5 V for use with a Graco level sensor. Level Sensor Alert Threshold 0 to 99% The alarm threshold must be lower than the alert threshold.
Setup Interval The interval defines how frequently the pump lubricates. For lubrication systems such as Series Progressive or Single Line Parallel, that have a varied lubrication event duration (due to environmental conditions such as temperature), the pump adjusts the idle time automatically to meet the interval requirements.
Operation Alerts and Alarms Additional support on alerts, alarms, and troubleshooting can be found at https://graco.com/G3Support. When the pump has detected an issue with the lubrication system, it may enter an alert or alarm state. During an alert: • The pump continues to operate.
If the lubricant is contaminated or has a high solids content, the pump element may need to be replaced. Replacement pump elements are available from your Graco Lubrication Equipment distributor. Alarm Types See Troubleshooting, page 55 for more information.
