Model S4000CH

5.1.4 F5

Unused

5.1.5 F6 Low Supply Voltage

This fault occurs if the supply voltage at the S4000CH drops below +18.5 VDC.

ACTION

- Ensure that the supply voltage is at least +20 VDC at the S4000CH.

5.1.6 F7 EEPROM Error

In the event of an EEPROM error, the user must recycle the power to potentially clear the
error. After power reset, the following may occur:

1) Unit returns to normal.

a. This indicates the EEPROM writing did not keep up to changing events or the

write cycle is too fast.

2) Unit goes to F2. The user must recalibrate after 1-2 minute sensor warm up.

This means the non-critical part of the EEPROM was corrupted.

This is probably caused by an event-logging problem.

There is a possibility any of the following may be corrupted.

i. Event logging data

ii. Modbus

settings

iii. HART

settings

iv. Calibration information

v. ARGC

setup

3) Unit returns to F7

a. This is a critical error. This fault occurs when an attempt to verify the

setup/calibration parameters just written to the EEPROM memory fails.

ACTION

- The unit must be returned to the factory or authorized service center for repair.

5.1.7 F8 Failure to Complete Setup

This fault occurs if the unit is left in setup mode for more than 6 minutes.

ACTION

- Exit setup mode. Enter setup mode again if it is necessary to change any user

selectable options.

5.1.8 F9 Gas Check Period Exceeded

If the S4000CH is left in the Gas Check Mode for more than six minutes or if test gas is left
on the gas check mode for more than 6 minutes, this fault will occur.

ACTION

- Place the magnet over the GM logo on the cover to return the unit to normal

operation.

5.1.9 F10 Switch Error

This fault occurs if the “remote reset”, “remote calibrate”, or the magnetic switch is closed for
more than two minutes.

NOTE:

If the ARGC is enabled, the grounded calibration switch does not go to fault.

ACTION:

Check the wiring on the remote reset and remote calibrate switches. Once the

short circuit is cleared, the unit will return to normal operation. If the magnetic switch is
