ICAD Overview
Before programming it is important to understand the functionality of the ICAD actuator:
1. The ICAD is a digital stepper motor. As such, it will count steps up and down from the
position it believes it is in. Every time, the ICAD is powered on, it will drive itself to the
closed position in order to re-establish its base point of reference. It will then move back
to the position corresponding to the signal it is receiving from the control wiring.
. The ICAD can be put into manual mode to move it (using the up and arrows) to a location
different from the location that the signal is telling it to be in
(see parameter ¡01, p. 6)
.
When in the manual mode, the display screen will be flashing and will continue to flash
flashing the % opening of the valve until the ICAD is taken out of the manual mode.
3. The ICAD can be operated in analog mode (for modulating operation) or in digital mode
for solenoid operation. The ICAD can receive a variety of control signals
(see parameter
¡03, p. 6)
and can send a valve position output signal to modulate another ICAD or to a PC
or PLC for monitoring.
(see parameter ¡06, p. 6)
4. Because the ICAD is employs a digital stepper motor, its speed can be adjusted to any
percentage of full speed through the parameter menu.
(see parameter ¡04, p. 6)
5. The ICAD can be connected to a 4 VDC UPS (Uninterruptible Power Supply) and can be
programmed for actions when the normal power has been cut and the ICAD is operating
off of the UPS power.
(see parameter ¡07 and ¡12 , p. 6)
1. In order to access the menu,
PRESS and HOLD the middle button () until the menu screen appears.
. Once you are in the menu, use the up (3) and down (1) arrow keys to move through the
list of parameters.
3. To display the current setting of a parameter press the middle button.
a. To change the value of a parameter setting, use the up or down arrow to establish
the new setting while in that particular parameter’s display mode.
b. Once the new setting for a parameter has been selected, push the center button to
save the charge and return to the menu.
4. Repeat this procedure for all parameters.
5. Exit from the parameter list by pressing and holding the middle button for seconds.
The ICAD will automatically exit if no buttons are pushed for 0 seconds.
