Operation
General Your ESRS is fitted with a range of indicators and controls to allow
easy configuration and use. This chapter explains the function and
operation of these and provides additional technical data where
appropriate.
Indicators There are two green LED indicators provided on the ESRS front panel:
OK and Enable.
The OK indicator relates the status of the applied power (either +5V
DC or +12V DC) and associated fuse. When the LED is lit, it indicates
that power is applied and the fuse is healthy.
The Enable indicator relates the status of the Enable input. When it is
lit, the Enable input is active and the ESRS is enabled.
Controls The ESRS provides controls for Line Speed, Acceleration, Rounding,
and Line Selection.
Line Speed
The Line Speed control of the ESRS allows the user to set the desired
line speed from the ESRS. The control is a 270 degree potentiometer
accessible from the front panel of the ESRS. For tamper avoidance, the
control is screwdriver operated. The function of this control is
dependent on whether the Option Switch is set to Unidirectional or
Bi-directional.
When Set To Unidirectional
When Unidirectional Mode is selected, zero speed occurs in the MIN
position and maximum speed occurs in the MAX position. The
direction of rotation in this mode is set by the Options switch.
