12.10 FID System Errors
This section describes the reported system errors.
Air flow deviation:
This error occurs when the difference between air flow and
air flow set point is higher than 5 cc/min. When this error is active, the flame
cannot be ignited.
Low air flow:
This error occurs when the air flow is below 10 cc/min. When
this error is active, the flame cannot be ignited.
Fuel flow deviation:
This error occurs when the difference between fuel flow
and fuel flow set point is higher than 5 cc/min. When this error is active, the
flame cannot be ignited.
Low fuel flow:
This error occurs when the fuel flow is below 10 cc/min. When
this error is active, the flame cannot be ignited.
Sample flow deviation:
This error occurs when the difference between sample
flow and sample flow set point is higher than 5 cc/min. When this error is active,
the flame cannot be ignited.
Ambient temperature deviation:
This error occurs when ambient temperature
is out of range. Ambient temperature must be between 5
C and 50
C.
F.I.D. temperature deviation:
This error occurs when the difference between
actual FID temperature and FID temperature set point is higher than 10
C. When
this error is active, the flame cannot be ignited.
Glow plug damaged:
A glow plug is used to ignite the detector. If the glow
plug is damaged, this error message is displayed. When this error is active, the
flame cannot be ignited. The glow plug must be changed.
Flame off:
This error occurs when the FID’s flame is off.
Sample flow reg. problem
: A fault with the sample pressure regulator. To clear
the error, reboot the system. If the error remains after rebooting, contact
Servomex for support.
Air flow reg. problem
: A fault with the air pressure regulator. To clear the
error, reboot the system. If the error remains after rebooting, contact Servomex
for support.
