Belt Spd Demand
This output is used to set the desired speed of the belt, via the motor speed
control (i.e. VFD or SCR drive).
Feedrate
This output transmits the actual feedrate, i.e. to an analog rate meter or chart
recorder.
Belt Load
This output transmits the actual belt load.
Belt Speed
This output transmits the actual belt speed. This can be used, for example,
to control the rate of a pre-feed device such that it is always proportional to
the belt speed.
Setpoint
This output transmits the actual setpoint. Note that this setpoint may be
received from several sources (i.e. Local, Network, Remote Analog, etc.).
Available
Selecting this parameter allows you to write a value to the analog output via
a network or serial connection, which will then be sent out the physical
analog output. It is not used by the GCM application. The value is written to
a register in floating point format, which will be scaled according to the
parameters under Numeric Data (see below).
Note, the name of the register used is GLO.AnaOutHijack, the number of
which will be dependent on the GCM firmware version. Contact Merrick
Customer Support for assistance if necessary.
Always Zero
This setting effectively “turns off’ the physical output, so that no power is
used.
Numeric Data
This menu contains numeric parameters that allow you to scale the analog
output to the process value it represents. The parameters are:
High mA ↑
Full Scale
Low mA
Zero ↓
Selecting any of the above parameters brings up the Numeric Data Entry
screen that allows you to assign or edit the numeric value.
