Hardener Sample Time
The allowable range of values for this parameter
is any integer from 0 seconds to 10 seconds.
This parameter allows the operator to program
how often (in accumulated seconds) the flow of
the slave channel is verified.
Hardener No Flow
The allowable range of values for this parameter
is 4 mA to 20 mA.
This parameter allows the user to program in the
current (in milliamps) below which the controller
assumes that no catalyst is flowing.
Hardener Flow On
The allowable range of values for the parameter
is 4 mA to 20 mA.
This is the value above which the controller will
assume that catalyst is flowing. It must always
be greater than the Hardener No Flow Parameter.
If the controller sees a value between hardener no
flow and hardener flow on, it examines the slope
of the current. As long as the current is increasing
while the gun is triggered, the controller assumes
catalyst is flowing. If the current is decreasing or
remains stable while the gun is triggered, the con-
troller will assume no catalyst flow and increment
the hardener sample time timer.

NOTE
Minimum Inlet Control Pressure
The allowable range of values for this parameter
is any integer value from 0 psi to 100 psi.
This is the minimum pressure that the E to P
transducer in the motor amplifier panel will be
allowed to go down to. Even if the fluid pressure
at the inlet of the pump is above the minimum inlet
fluid pressure setpoint, the control (pilot) pressure
from the E to P transducer will not go below this
setpoint. This can be used as an offset to keep
the fluid regulator at its cracking point to allow for
rapid response by the fluid regulator at the trigger
on points.
Inlet Kp
The allowable range of values for this parameter
is any integer from 0 to 65,535. The value has
no units.
This value is the proportional gain factor for the
PID loop that controls the inlet pressure to the
pump.
Inlet Ki
The allowable range of values for this parameter
is any integer from 0 to 65,535. The value has
no units.
This value is the integral gain factor for the PID
loop that controls the inlet pressure to the pump.
Inlet Kd
The allowable range of values for this parameter
is any integer from 0 to 65,535. The value has
no units.
This value is the derivative gain factor for the PID
loop that controls the inlet pressure to the pump.
Inlet Deadband
The allowable range of values for this parameter
is any integer from 0 to 65,535. It is expressed
in PSI.
This value is the deadband for the PID loop that
controls the inlet pressure to the pump.
