Flowserve ESP-DC Electronic Servo Positioner Manuel d'utilisateur télécharger pdf

Automax electric actuators with servo control are

factory adjusted for 90 degree operation and

shipped in the full clockwise position as viewed

from the motor side.

ESP-DC Configuration

The ESP-DC board provides a variety of options for

the user. These options are made available with the

configuration of the jumpers JP1-JP6. See the table

at the bottom of this page for a summary of the

available configurations.

Servo Control Input Options

1 Connect input signal to terminals marked +IN

and -IN on the junction block J3.

A 4-20mA Current Input (100 Ohm sink) - JP1

set to "A" (left) position. This is supplied as

standard.

B 2-10 Vdc Input - JP1 set to "B" (right)

position.

Direct or Reverse Acting

1 Standard units are direct acting:

Low input (e.g. 4 mA) = CW*

High input (e.g. 20 mA) = CCW*.

2 To make reverse acting, move jumper JP2 to

the 'R' (right) position.

Fault Detection and Action

1 FAULT conditions occur when the torque of the

DC motor exceeds a preset maximum value.

This feature is used to protect the valve

hardware, the actuator hardware, and alert the

user that there may be an obstruction in the

valve. When a fault occurs, the LED labeled

'FLT' will be lit, and the actuator will stop. The

actuator must receive a signal to drive in the

opposite direction in order to reset the FAULT

condition.

2 By running a wire to the FLT terminal strip

location on junction block J3, a signal can be

returned to indicate if a FAULT occurs. Jumper

JP3 can be used to set the FLT terminal output

to the following:

A High - Jumper JP3 set to "P" (left) connects

the FLT terminal to the Power Supply "+"

when a FAULT condition occurs.

B Low - Jumper JP3 set to "N" (right) shorts

the FLT terminal to the Power Ground "-"

when a FAULT condition occurs.

Low Power Operation

1 The factory configures the ESP-DC for full

functionality. If low power consumption is

required, the FLT output and the LED's may be

disabled.

A FLT - to disable the FLT output, move JP4

to the "N" (right) position.

B LED's - to disable the LED's, move JP5 to

the "N" (right ) position.

Loss of Input Signal

1 If the input signal to the actuator is lost, the

ESP-DC is configured to turn full CW* as a

safety precaution.

2 The Loss of Input action above can be disabled

by setting JP6 to the "S" (lower) position. In

this case the actuator will simply stop if the

Input Signal is lost.

ESP-DC Jumper Configuration

JUMPER Factory Setting Option

JP1 - INPUT A : 4-20mA B : 2-10 Vdc

JP2 - ACTION D : Direct R : Reverse

JP3 - FLT output P : +Vcc N : GND

JP4 - FLT enable Y : Enable N : Disable

JP5 - LED enable Y : Enable N : Disable

JP6 - Loss of

R : Full CW* S : Stop

* For Reverse Acting, the CW and CCW directions marked with a * are reversed.
