P6 Regen High Temperature

Passive Alarms

Problem

Possible cause

Solution

P5 Return Air High Temperature – If the return air temperature is between 150 and 180°F (65.6 and 82.2°C).

P6 Regen High Temperature

–If the regeneration tempera- ture exceeds the high tempera- ture limit for the specified time. Default values are 450°F (232.2°C) for 20 sec.

P7 Regen Low Temperature

–The regeneration tempera- ture is less than the low tem- perature setpoint for the speci- fied time. Defaults are 350°F (176.7°C) for 20 sec.

P8 Regen Temperature Loop Break – The regeneration tem- perature is outside of the oper- ator entered deviation alarm band (see Regen Temperature Deviation passive alarm) and the regeneration temperature is not moving towards the set- point at a rate greater than specified. Default values are 36°F (2°C) over 20 sec.

The hopper does not contain enough material.

You are drying at a high drying tempera- ture (above 250°F [121.1°C]) or running at low throughputs.

If an optional aftercooler is installed, it does not have enough water.

The aftercooler coils are dirty.

The air hose connections are loose.

One of the solid state relays (SSRs) failed in the closed position.

The regeneration RTD is loose or has fallen out.

The regeneration heater has failed.

The regeneration RTD is loose or has fallen out.

The return air RTD has failed.

The regeneration heater has failed.

The regeneration RTD is loose or has fallen out.

Make sure your material supply system is working properly.

Add an optional aftercooler, if one is not currently installed.

Turn on the water supply, or fix any leaks or blockages.

Clean the aftercooler coils.

Tighten all air hose connections.

Replace the failed solid state relays (SSRs).

Check the regeneration RTD and tighten if needed.

Check the heater fuses, and resistance across each leg of the process heater.

Check the regeneration RTD and tighten if needed.

Replace the return air RTD.

Check the heater fuses, and resistance across each leg of the process heater.

Check the regeneration RTD and tighten if needed.
