1.1 Introduction

Your new +GF+ SIGNET 9030 Intelek-Pro pH
Controller has been specifically designed for pH
measurement process control applications. The
controller's compact 1/4 DIN enclosure (front) is
NEMA 4X/IP65 rated and ideal for installation
into instrumentation panels with limited space.

Modular "plug-in" input/output option cards allow
you to customize your pH controller to your
system's requirements. The controller's unique
"slide-out" chassis design makes option installation
fast and simple. Smart self-configuring
microprocessor based circuitry automatically
inventories installed options during power-up,
allowing you to upgrade your system in seconds
without the need for additional equipment.

The unit's front panel features a highly visible

4.5-digit (seven segment) and 8-digit (alphanu­meric) liquid crystal display with adjustable con­trast. Active pH, mV, temperature in °C, and
alarm relay status information is quickly accessed
at a glance. During calibration the user is
prompted with clear step-by-step instructions on the
unit's front panel display.

2.1 Mounting Instructions

The +GF+ SIGNET Intelek-Pro pH Controller's 1/4
DIN enclosure is specifically designed for panel
mounting. Adjustable mounting brackets allow
mounting in panels up to one inch (25 mm) thick.
An adhesive template and instructions are included
to insure proper installation.

For outdoor and/or stand alone installations the

2.4 2-Relay Output Connections

The 2-Relay option provides two relays for external
device control. Each relay's contacts are rated for
5 A maximum. Both NO and NC contacts may
be used simultaneously or individually as shown.

Proportional Control Wiring

2.5 Dual Proportional Relay Connections

The Dual Proportional Relay Card provides two
relays (3 and 4) for external device control.
Proportional or alarm operation is selectable
during calibration. Both relays MUST be like
configured, meaning one relay cannot be selected
for proportional operation while the other is
selected for alarm operation.

If alarm operation is selected, relays 3 and 4
operate as on/off controls similar to relays 1 and

2. The main distinction is the lack of the normally
closed (NC) contact. Refer to Figure 5 pg# 7 for
further instructions.

If proportional operation is selected, relays 3 and
4 are configured to provide a varying pulse rate to
control metering pumps. Relay 3 is dedicated to
low range control and relay 4 to high range
control.

Note:

rated as 5A @ 250 VAC or
5A @ 30 VDC maximum
resistive load.

Relay contacts are

To reduce the possibility of
noise interference, separate
AC relay lines from input/
output lines.

2.6 Verifying Analog Outputs

Installed output options can be configured to either
of the unit's rear analog output terminals: ANL1 or
ANL2. Configuration is determined by which
sockets the options are installed. Options installed
in option socket #1 are configured to the rear
ANL1 terminals, options installed in socket #2 are
config-ured to the rear ANL2 terminals, see
section 4.4.

Prior to connection, determine which options are
configured to terminals ANL1 and ANL2 as
follows:

1. Apply power to unit.

2. Press:

ENTER

Available input/output options are

individually prompted on the display.

3. Record option configurations for ANL1 and
ANL2 in the spaces provided. This information is
necessary for wiring analog outputs in the next
section.
