In many industrial applications it is necessary to be able to control a device
manually. Often a potentiometer or rotary switch is used, but this method can
be too coarse and not easily repeatable. Texmate have developed a versatile
and easy-to-use selection of manual stations, using their Tiger 320 Series
controller, that produce an accurate, digitally controlled and scaled 4 to 20
mA or 0 to 10 V output.
The digital value shown on the controller display is proportional to the
scaled output and is adjusted directly through the front panel buttons to
ensure precise and repeatable operation.
The auto manual station provides an automatic and manual analog control output
to PLCs, process controllers, speed controllers, and actuated devices. Input
to the station can be from a PLC or from almost any input sensor type.
The input signal automatically controls the analog output from the auto manual
station to the controlled device in the auto mode. If the operator needs to
manually control the analog output independently of the input signal, the
station can be switched to the manual mode using
the front panel PROGRAM button. The auto manual station can then be returned
to the auto mode when required by the operator. The control output will then
ramp up or down at the programmed rate-of-change to provide bumpless transfer
between modes.
The rate-of-change is the transfer rate of the control output signal changing
from the manual mode back to the automatic control output signal of the auto
mode.
This is set by the operator as displayed counts per second by pressing the
PROGRAM and DOWN button at the same time and entering the [rAtE] menu.
Manual mode control output signal high low limits can also be set.
