Serial Analog Module - Operation

OPERATION

The Serial Analog Module provides a pneumatic

pressure signal output which is proportional to the

voltage input. Each module contains two channels

of control. The voltage input can be provided by

various methods; by a front panel control, by an

external 1-10 VDC signal, an external 0-10 VDC,

or external 4-20 mA signal. The front panel control

has a detent at full CCW. In this detent position,

the output responds to the external voltage input.

When this control is rotated CW from this detent,

the output responds to the position of the front panel

control. A "Local" signal is provided to indicate

that the output is controlled by the front panel. A

"Stable" front panel indicator and signal output

indicate that the output pressure has reached the

level set by the input signal.

CONFIGURATION

1. "Open" position for pilot lines less than 50-ft.

of 5/32-inch tubing. "Closed" (opposite the

open position) for pilot lines more than 50-ft.

of 5/32-inch tubing.

2. Future Use

3. Future Use

4. "Open" position for 0-10 VDC remote input in

voltage mode.

"Closed" (opposite the open position) for 1-10

VDC remote input in voltage mode.

Before installing module, make sure the

o-rings (7554-03), located on the edge

connector of each pneumatic valve, are

in place and fully seated. Prior to install-

ing, put a small amount of lubricant on the

surface of each o-ring to prevent shearing

when installing.

NOTE

When one output is used to pilot a volume booster

(regulator), the volume booster must have a non-

bleed pilot, such as P/N: A11111.00. Use of a

volume booster with a bleed pilot will cause fluc-

tuating output pressure. When using the Serial

Analog Module for a retro-fit application, refer to

the last page of this Operation section for details.
