Maintenance

The Maintenance screen gives the options to change the Panel Setup Times and modes. Under the Panel

Setup Times the user can adjust the Startup delay, High Pressure on time, number of blow backs, and the

time between blowbacks. The modes available are the calibration mode, off mode, maintenance mode,

and the startup mode. In maintenance mode the user can choose to turn on or off the High pressure

solenoid, pressure release solenoid, the pump, and choose the probe selection. The mode check alarm

time is adjustable in the maintenance screen as well.

Modes

Start Up Mode

Start up mode is the first mode that the sample panel goes into upon being enabled. Start up mode allows

pressure to be created within the lines and give the flow detector time to stabilize. The sample panel

enters start up mode every time that the pump turns on. If there is a low flow condition or the line is

clogged during start up mode the sample panel goes into an error condition and the PLC energizes the

trouble relay and sends a signal to the DCS signaling that maintenance is required.

Normal Mode

Normal mode occurs immediately after start up mode and is maintained during normal sampling

conditions. Normal mode is defined as: the pump operating correctly, the flow detector is within normal

range and the panel is not in maintenance or blowback mode.
