PRESS TOO HI:

Gage pressure has gone above the Hi alarm value set in the variables.

TEMP TOO LOW:

Temperature has gone below the Lo alarm value set in the variables.

TEMP TOO HI:

Temperature has gone above the Hi alarm value set in the variables.

Compensated flow has gone below the Lo alarm value set in the variables.

EXCESSIVE FLOW:

Compensated flow has gone above the Hi alarm value set in the variables.

ANALOG OUT ERROR:

4-20mA output is broken or Compensated flow has exceeded the 20mA value set in the variables.

OPERATOR FORGETS SECURITY LOCKOUT CODE

If the authorized programmer of the instrument forgets the security code and is locked out, follow this procedure:

A. Scroll through the menu to the Lock/Unlock menu. Press the key.
B. At the prompt, enter the code 00000 using the keypad.
C. The instrument will display a message “CALL IN CODE” and a 5-digit number.
D. Call the manufacturer and ask for the proper Customer Service Personnel.
E. Customer Service will ask for a 5 digit CALL IN CODE and will give back a 50digit RETURN CODE that was

generated by a computer.

F. Enter this 5 digit RETURN CODE using the keypad.
G. Five chances to enter the RETURN CODE are allowed, after which this procedure will have to be repeated.
H. Once the new 5 digit code has been successfully entered, it will unlock the Flow Computer.
I.

It is the programmer’s responsibility to reset the instrument with a new 5 digit lockout code.

J.

If, at a later date, you are locked out of the instrument again, you will have to call and repeat this procedure. A
new CALL IN CODE will be generated by the instrument.



PULSE INPUTS ARE NOT COUNTING ON THE INSTRUMENT

A. Check the voltage of the pulses. They must be between 3-30V, and not less than 3V or negative.
B. Check pulse width. The pulse width of the signal must be consistent with the filter that you have selected. If this is

not the case, change the filter value.



INSTRUMENT NEEDS TO BE TOTALLY RE-INITIALIZED TO CLEAR OUT THE MEMORY

Power up the instrument and press the and the keys at the same time. This will totally re-initialize the
instrument. All parameters will be reset to their default values. The unit will require you to input the parameters that
have null values and select the various options available.
