Automax Valve Automation Systems
Installation, Operation and Maintenance Instructions
Page 2 of 4
This instruction set contains information for proper setup
of the Controller Card. Additional actuator mounting and
maintenance information may be found in appropriate
instruction sets.
Automax CE Electric Actuators are factory adjusted for 90
degree operation and shipped, as viewed from the motor
side, in the full clockwise position.
Control Input Connections
1.
Connect remote directional input wiring to
H=CW/L=CCW and RET terminals (TB1 pins 5
and 6), per Page 3 input details.
2. Connect remote braking input wiring, when
required, to the H=RUN/L=STOP and RET
terminals (TB1 pins 3 and 4), per Page
3 input details.
Initial Setup for Valve Port Alignment
1.
Set the six (6) on-board local control
switches to BRK, LOCAL, LOCAL, CW, LED, RLY.
2. Ensure CW limit cam has engaged CW limit
switch with valve in full clockwise position.
3. Connect proper DC voltage supply to +++/
POWER and RET terminals (TB1 pins 7 and
8), noting proper voltage level and polarity.
Label on motor gearbox identifies proper
actuator voltage rating. Voltage input is diode
protected against + / - reversal, but actuator
will not respond if polarity is reversed.
4. Apply power and observe LED CW is blinking
when BRK / RUN is in run.
5. Set CW/CCW switch to CCW, and observe
LED CCW is lit, and LED CW is out. Motor
begins to turn, and valve begins to open.
Note: If LED F (fault) lights, adjust I SENCE
pot 1/8 turn clockwise, clear fault by turning
BRK on or by toggling direction control switch.
6. Set BRAKE ON/OFF switch to ON and observe
motor stops and LED BRK is on. Set BRAKE
ON/OFF switch to OFF and observe motor
turning.
7. Set BRAKE ON/OFF switch to ON when
valve reaches final counterclockwise position, and
set CCW limit cam to engage CCW limit switch.
Installation and Operating Instructions
Note: If CCW limit cam engages limit switch before
attaining desired position, set BRAKE ON/OFF
switch to ON, adjust cam to disengage switch, and
continue with Step 6.
8. Set CW/CCW switch to CW, BRAKE ON/OFF
switch to OFF, and observe CW limit switch/cam
stops motor when valve reaches proper
clockwise position.
Note: Set BRAKE ON/OFF switch to ON if limit cams
require adjustment. This eliminates actuator from
rotating during cam/switch adjustments.
9. Repeat clockwise and counterclockwise position
checks and ensure valve limits are correct.
Speed and Current Limiting Adjustments
TORQUE and I SENSE adjustments are dynamic settings
that vary by application and affect CW and CCW directions
equally. Toggle CW/CCW switch to cycle actuator while
making adjustments.
1. Set the TORQUE (speed) adjustment
counterclockwise, when needed, to slow
actuator stroke speed.
2. Setting the I SENSE (current limiting)
adjustment counterclockwise will reduce the
amount of motor current needed to trigger the
fault latch circuit. The I SENSE adjustment should be
set to allow CW/CCW motor reversals "on-the-fly".
Note: Check to ensure adequate power is
available at times of normal high current conditions.
Verify the I SENSE adjustment allows motor to
operate "into" and "off of" valve seat.
3. Set the two (2) on-board LOCAL/REMOTE
switches to REMOTE. This will disable CW/CCW and
BRAKE ON/OFF local switches, while transferring
control to remote inputs connected at TB1.
4. Verify proper operation from the control room.
5. Set LED switch to "OFF" for power savings, if desired.
