QuickCal Procedure
The following is a quick calibration procedure. For more details regarding the
calibration and features of your DHC-100, please see the pages following this
procedure.
General
The MODE button selects a particular function, or mode, and the indicator for the
selected mode turns on steady. Pushing the MODE button saves any new setting
of the current mode before switching to the next mode. The adjust up (
) and
adjust down (
) buttons are used to make adjustments to current mode.
1.
Apply power to the actuator on Connector J2: terminal #1 (neutral), terminal
#2 (line), and terminal #3 (earth). There is no need for a signal connection during
calibration.
2.
Push the MODE button until the yellow “MANUAL/FB POT CAL” LED is
illuminated. The LED may be flashing (at different speeds) through the next
several steps. This is expected and will be explained.
3.
Use the adjust buttons (
and
) to move the actuator and verify that the
limit switches are set past the desired open and closed positions; then move the
actuator to mid stroke.
4.
If LED is solid, proceed to step 7.
5.
If LED is flashing, loosen the gear on the actuator shaft and rotate the
potentiometer gear until the LED is no longer flashing, but on solid - this indicates
the center of the potentiometer’s travel. Note that the LED will flash at a slower
rate the farther away from the mid position it gets. Once the LED is on solid
tighten all gears.
6.
Push the MODE button until the “CLOSE” LED is illuminated. Use the adjust
buttons (
and
) to drive the actuator to the desired closed position. Ensure
that the close limit switch does not engage.
7.
Push the MODE button until the “OPEN” LED is illuminated. Use the adjust
buttons (
and
) to drive the actuator to the desired open position. Ensure that
the open limit switch does not engage.
8.
Please skip to
Aux Open/Close Setup
if optional Transmitter with Relays is
installed; otherwise continue to the next step.
9.
Push the MODE button until the “COMMAND TYPE” LED is illuminated. Use
the adjust buttons (
and
) to select appropriate input signal (4-20mA, 1-
5VDC, 0-5VDC, 0-10VDC, 2-10VDC or Digital). If 0-5VDC or 0-10VDC is
