13. At this point the user has the option to establish a
password. Once a password has been set, the 4200 will
always prompt the user for a password, before pro-
gram changes can be made. When no password or the
wrong password is entered, the 4200 will go back to
the normal display. THE ESTABLISHMENT OF A
PASSWORD IS OPTIONAL. If locking the 4200 with a
password is not needed, enter “000000” and the 4200
will operate unlocked. **
Button operation:
“Program” = progress to next screen regardless of
where cursor is positioned
“Enter/Next” = move cursor left one position
“K-factor” = move cursor right one position
“+” = increments number where cursor is posi-
tioned
“-” = decrements number where cursor is posi-
tioned
“Reset” = replaces numbers with default and re-
turns the cursor to the right most position
** It is highly recommended that the
password function not be used unless it
is required. If a password is required
write down the password in the manual
and keep in a secure location. If you
forget the password you must con-
sult the factory for procedures on
how to reset the current password.
14. Now the 4200 will prompt for user to accept
the password. Display should read 000000 in RATE
area of LCD if no password is required
Button operation:
“Program” = return to password screen (step 14)
“Enter/Next” = accepts password and exits program
mode
“K-factor” = return to beginning of setup
“+” = return to password screen (step 14)
“-” = return to password screen (step 14)
“Reset” = return to password screen (step 14)

Changing Batteries
New batteries can be purchased through INVALCO or
our distributors and replaced in the field.
WARNING - To prevent ignition of flammable or
combustible atmospheres, read, understand, and
adhere to the manufacturer’s live maintenance pro-
cedures.
Replace battery with an INVALCO battery assembly
ONLY. Battery assembly part number is P524017. The
model 4200 is designed to operate on one battery.
NEVER attempt to power the unit with two battery as-
semblies or with a non-INVALCO battery assembly.
There is one Lithium battery pack in each instrument and
care must be taken to replace so that there is always power
connected to the memory. Connect the new battery pack
into J3 or J4 before disconnecting the old battery. Failure to
not supply the board with continuous power will result in loss
of setup parameters and totals. Please dispose of old
batteries by sending them to an Approved Battery
Recycle Location.
Typical Connections
Flowmeter Input
The Model 4200 input circuit which will accept signals
from most pulse or frequency producing flowmeters.
The input will interface directly to:
Turbine Flowmeters
For flow meters with coils, the minimum input voltage is
20mV P-P. See the drawing below and sketches on the
next two pages for hook-up information.
1. Squarewave, CMOS or Pulse
2. Reed or Switch
5. Coils (Magnetic Pick-up)
Wiring
When connecting the 4200 it is good practice to use a
shielded cable. The shield should be connected to
earth at one end of the cable. The other end of the
shield should not be connected.
