Chapter

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.
