Introduction
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 (alphanu-
meric) liquid crystal display with adjustable con-
trast. 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.
The +GF+SIGNET 9030 Intelek-Pro pH Controller
is fully compatible with all +GF+SIGNET pH
sensor products, yet also accepts other analog
inputs, such as 4 to 20 mA or 0 to 5 VDC etc.

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.

Device A is powered during
normal operation. Power is

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: Relay contacts are
rated as 5A @ 250 VAC or

resistive load.
To reduce the possibility of

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.

3.1 Introduction
All the functions which can be modified are
contained in three menus:
The CAL (calibrate) menu contains those functions
which pertain to the input signal and how it is
interpreted by the instrument (i.e. pH standard, pH
slope). The CAL menu also provides access to the
security code and display contrast features.
The RELAY menu contains all the functions neces-
sary to control any output relays, such as relay
Note: The maximum loop impedance for the 4 to 20 mA/0 to 20 mA output is 425 Ω .
The minimum load impedance for the 0 to 5/0 to 10 V output is 1 K
Ω (1000 Ω ). To
reduce the possibility of noise interference, separate output lines from AC power/relay lines.

calibration using the

3.2 Calibration Menu, pH Sensor Inputs
• If you are installing a new input card, see
section 4.5 (input card introduction mode) prior
to performing system calibration.
• New pH electrodes require you to "set temp"
before setting standard (STD) and slope (SLP).
Allow approximately 3-4 minutes for the sensor
temperature to stabilize. This adjustment is
normally needed only at time of new electrode
installation.
• It is recommended to perform two-point
calibration routinely to adjust for electrode
change. Example: 1. Set STD for 7.00 pH
(0 mV). 2. Set SLP for 4.00 pH (+177 mV) or
10.00 pH (-177 mV).

3.4 2-Relay Operation
The 2-Relay option allows you to configure indi-
vidual setpoints, LO or HI operation, and hysteresis
values for two independent on/off relays.
• Relay Setpoints: Setpoints represent the pH at
which each relay is energized.
• Relay Hysteresis: Hysteresis values directly
effect the LO and HI relay modes, specifying how
far the pH will rise above (LO Relay Mode) or fall
below (HI Relay Mode) each relay's setpoint prior
to de-energizing the relay. The main purpose for
hysteresis is to eliminating relay "chatter", caused
by a pH hovering around a relay's setpoint. Hyst-
eresis values are programmed in direct pH units
and must be less than the corresponding relay set-
point, maximum 4 pH units (a pH setpoint of 3.0
cannot have a hysteresis of 4.0). Hysteresis only
applies when exiting an alarm condition.
• LO Relay Operation: In LO operation, the relay
is energized when the pH drops below the set-
point, and is de-energized when the pH rises
above the setpoint plus hysteresis. See Figure 8
• HI Relay Operation: In HI operation, the relay
is energized when the pH rises above the setpoint
and is de-energized when the pH falls below the
setpoint plus hysteresis. See Figure 9
3.5 Dual Proportional Relay Operation
The dual proportional relay option allows you to
configure relays 3 and 4 to operate as dual
proportional control (pulse) relays or as on/off
relays which operate identical to the 2-Relay
option.

The dual proportional relay configuration is
primarily designed to control external metering
pumps. Setpoints, deviation ranges, and maxi-
mum pulse rates are selected via the relay menu.
• Setpoint: pH value at which relay pulsing be-
gins. Relay 3 setpoint must be less than or
equal to relay 4 setpoint.
• Deviation: Number of pH units from setpoint to
maximum pulse rate. Deviation values cannot
extend beyond the 0 to 14 pH scale.
• Pulse Rate: Pulse rate selected from 0 to 120
pulses per minute maximum.
