(a) UNPACKING THE TOTALIZER
a.1 Inspect Package for External Damage
Your Totalizer was carefully packed in a sturdy cardboard carton, with antistatic cushioning materials to withstand shipping shock. Upon receipt, inspect
the package for possible external damage. In case of external damage to the
package contact the shipping company immediately.
a.2 Unpack the TOTALIZER
Open the carton carefully from the top and inspect for any sign of concealed
shipping damage. In addition to contacting the shipping carrier please forward a copy of any damage report to your distributor or Aalborg7 directly.
When unpacking the instrument please make sure that you have all the items
indicated on the Packing List. Please report any shortages promptly.
a.3 Returning Merchandise for Repair
Please contact the customer service representative of your distributor or
Aalborg7 if you purchased your Totalizer directly, and request a Return
Authorization Number (RAN). Equipment returned without an RAN will
not be accepted. Aalborg7 reserves the right to charge a fee to the customer
for equipment returned under warranty claims if the instruments are tested to
be free from warranted defects.
Shipping charges are borne by the customer. Items returned "collect" will
not be accepted!
It is mandatory that any equipment returned for servicing be purged and neutralized of any dangerous contents including but not limited to toxic, bacterially infectious, corrosive or radioactive substances. No work shall be performed on a returned product unless the customer submits a fully executed,
signed SAFETY CERTIFICATE. Please request form from the Service
Manager.

(b) DESCRIPTION
MODEL TOT-10: Totalizer designed to be used with existing models of GFM
mass flow meters and GFC mass flow controllers (calibrated for given flow
rate specified on the back label). It can be connected to the modular jack
instead of the LCD display, or optionally with the additional connector (CBLTOT-10) in parallel with the LCD display. Mechanically TOT-10 can be
installed on the top of the LCD display with two brackets and screws (supplied
only for model TOT-10).
MODEL TOT-05: Totalizer designed to be used with any transducer which has
0 to 5 Vdc output signal and time based engineering units. (i.e. units per second, units per minute, units per hours) It has to be connected to 12 Vdc power
source and 0 to 5Vdc voltage source with additional cable. It is calibrated for
given flow rate specified on the back label.
(c) FEATURES
The Totalizer takes analog output flow signals of 5 to 10 Vdc from the GFM or
the GFC models, or 0 to 5 Vdc from other transducers. It integrates and accumulates up to 7 digits of direct engineering units for the given gas and flow
rate (i.e. standard liters, standard cubic centimeters, etc.). In order to reduce
low signal (noise) totalizing, provision is made for 1% cut off schematic which
allows to accumulate only flow rates which exceeded 1% F. S.
