ATF System with C410:V3 Controller
User Guide
The Basic Set-Up screen will display the parameters in the following tables:
Field
Description
Process Set Up
Groups the following fields:
Pump Model No
Press to select Pump Model No ATF4, 6, 8, 10, 10-R
Control Mode
Press to select Control Set Point units (FLOW or TIME)
Alarm Delay(min)
The amount of time in minutes the controller will stay in warning
condition before switching to alarm condition. (If 0 is entered
system will remain in warning condition.)
Slope Function Enable
Integrates P2 slope at Delay Time to extrapolate Cycle Switch
Pressure. See warning below.
Bioreactor pressure
Expected bioreactor operating pressure
∆
height
The height difference between bioreactor liquid level and middle of
Diaphragm Pump (in cm)
P2 limits
Sets P2 upper and lower allowable limits
HiHi Alarm Set Points
Sets a high limit on P2 pressure during the P-Flow Cycle
If P2is ≥ HIHI, follow with ALARM and Syste
m Stop
LoLo Alarm Set Point
Sets a low limit on P2 pressure during the E-Flow Cycle
If P2is ≤ LOL, follow with WARNING
Alarm Delay (msec)
Delays response to HIHI and LOLO Set Point. If the alarm parameter
is set for 0 minutes it will remain in a “Warning” state. If the field is
set 1 – 50 minutes, the system will go into an “Alarm” state should
the condition for the alarm persists for the set elapsed time defined
in this parameter. This will put system in a halt condition.
Pump Parameters
Groups Diaphragm Pump Parameters :
P-Pressure Offset (psi)
Pressure cycle: Pressure Offset or-Over pressure Set Point (P-OSP1)
value (psi) above P2 to switch from Flow (or Pressure) cycle to
Exhaust
E-Pressure Offset (psi)
Exhaust cycle: negative Over pressure Set Point (E-OSP2) value (psi)
below P2 to switch from Exhaust cycle to Flow or Pressure cycle
P-Delay (%)
Sampling point of sP2 during the Pressure cycle (% of total cycle
time, preset range 10 to 90%)
E-Delay (%)
Sampling point of sP2 during the Exhaust cycle (% of total cycle time,
preset range 10 to 90%)
P-Overtime (%)
Sets the overtime limit to the Pressure cycle (% of calculated cycle
time)
E-Overtime (%)
Sets the overtime limit to the Exhaust cycle (% of calculated cycle
time)
