Installation Considerations
Installation and maintenance of the ION8600 meter should only be performed by qualified, competent personnel
that have appropriate training and experience with high voltage and current devices. The meter must be installed in
accordance with all local and national electrical codes.

DANGER
Failure to observe the following instructions may result in severe injury or death.

‹During normal operation of the ION8600 meter, hazardous voltages are present on its terminal strips,
and throughout the connected potential transformer (PT), current transformer (CT), digital (status) input,
control power and external I/O circuits. PT and CT secondary circuits are capable of generating lethal
voltages and currents with their primary circuit energized. Follow standard safety precautions while per-
forming any installation or service work (i.e. removing PT fuses, shorting CT secondaries, etc).
‹The terminal strips on the meter base should not be user-accessible after installation.
‹Do not use digital output devices for primary protection functions. These include applications where the
devices perform energy limiting functions or provide protection of people from injury. Do not use the
ION8600 in situations where failure of the devices can cause injury or death, or cause sufficient energy to
be released that can start a fire. The meter can be used for secondary protection functions.
‹Do not HIPOT/Dielectric test the digital (status) inputs, digital outputs, or communications terminals. Refer
to the label on the ION8600 meter for the maximum voltage level the device can
withstand.

CAUTION
Observe the following instructions, or permanent damage to the meter may occur.

‹The ION8600 meter offers a range of hardware options that affect input ratings. The ION8600 meter’s
serial number label lists all equipped options. Applying current levels incompatible with the current inputs
will permanently damage the meter. This document provides installation instructions applicable to each
hardware option.
‹The ION8600 meter’s chassis ground must be properly connected to the switchgear earth ground for the
noise and surge protection circuitry to function correctly. Failure to do so will void the warranty.

I/O Application Precautions

Consider the following when digital input/output devices are used for fast
control schemes or are used to perform critical equipment control operations
(e.g., breaker trip, etc.):

‹ Connect to external equipment with an intermediate mechanism, allowing

relay control to be completely disabled for servicing.
‹ The worst-case state change latency for the I/O Expander’s digital output
devices is 20 ms; worst-case state change latency for digital input ION
modules in the meter is 40 ms.
‹ When power or communications to the device is lost, the meter cycles
power in the I/O Expander and all digital outputs switch to an off state.
Once the I/O Expander regains power or restores communications to the
meter, the digital outputs’ states is updated by the meter.
‹ When the I/O Expander has powered down and powered back up, test
the digital outputs of the I/O Expander to ensure that all control conditions
occur as expected.
‹ After all control operations are verified, enable relay control of the
external equipment.

NOTE
Timestamp resolution for device state changes is ± 2 ms.

B. Set up the Digital Outputs

The Digital Output and Pulser modules control the digital output hardware
ports. You must use Designer to create and configure these ION modules.

NOTE
Your meter template may have factory configured Digital Output, Calibration
Pulser or Pulser modules.

To setup the digital outputs:

1. Once you have connected the external I/O field equipment to the digital
output ports, run Designer, and open the meter template.
2. If required, create a Digital Output, Calibration Pulser, or Pulser module
for each output port you are going to use.
3. Link the Source input of these modules to a value you want to reflect
through the digital outputs.

Ensure that the module Port setup register matches the I/O Expander output
you want to control. If the port you want to use does not appear in the Port
setup register list, that port is in use by another module. Edit the Port setup
register of the module using that port and set it to NOT USED – the port is then
available to other modules.

Step 8: Configure Analog Outputs
A. Set up the analog outputs
1. Once you have connected the external I/O field equipment to the
analog output ports on the I/O Expander, run Designer, and open the
meter template.
2. If required, create an Analog Output module for each output port you are
going to use.
3. Link the Source input of these modules to a value you want to reflect
through the analog outputs.
4. Use ION Setup to configure the settings of the controlling module to
match requirements. Settings in these modules are:

on the analog output hardware port.

Sets the measured value that will

Zero Scale -1 x 109 to 1 x 109 N/A create the minimum possible output
on the analog output hardware port.

Ensure that the module’s Port setup register matches the I/O Expander’s
output you want to control. If the port you want to use does not appear in the
Port setup register list, that port is in use by another module. Edit the Port
setup register of the module using that port and set it to NOT USED – the port
is then available to other modules.

B: Set the Zero and Full Scales

You control external devices by delivering a specific current or voltage that is
proportional to the source input. This is done by setting the Full and Zero
Scale setup registers and the hardware Port that the output is sent to. You use
Designer software to configure these setup registers in the Analog Output
module.

The Zero Scale setup register defines the source input value that creates the
minimum current output on the analog device.
The Full Scale setup register defines the source input value that creates the
maximum current output on the analog device. The Full Scale is determined
by the input to the Analog Output ION module (which is commonly
connected to kW). The Full Scale value is the maximum kW expected.
The following table describes setting your Zero Scale and Full Scale to use a
limited portion of the output's range.

 NOTE
This table assumes the source input varies between zero and the full scale
setting. If the source input falls below zero the output will not be within the
desired Output Range.

Step 9: Configure Advanced I/O
ION Modules facilitate the operation of the I/O Expander Digital Input,
Digital Output, and optional Analog Output ports. You can configure many
meter setup functions using ION software. You can customize the meter
template using Designer.

A. Set up Energy Pulsing

The area labeled “Energy Pulse (Hardware Port RC1-4)” contains four
Integrator modules (labeled kWh del, kWh rec, kVARh del, kVARh rec) and
four Pulser modules (labeled kWh del pulse, kWh rec pulse, kVARh del pulse,
kVARh rec pulse).

An Integrator module integrates its Source input, then sends a pulse to its
Trigger output when the integrated value reaches the Value/Pulse setting. The
Pulser receives the trigger, and sends the pulses with the Pulse Widths to the
hardware channel specified in the Port setup register.

Configure the values as follows:

Parameter to change Action

By default, these eight modules are not

Pulsing configured. Right-click near the center of
the modules to access the setup registers.

Modify the Port setup register and choose

Port
another hardware channel from the list.1

Change an Integrator module Value/

Pulse setup register to adjust how much
Pulse rate
energy the module accumulates before it
sends a pulse to a Pulser module.

The Pulse Width setting specifies the

width of the pulses that the Pulser module
Pulse width sends to the hardware channel. Modify
the Pulse Width value to change the
width, in seconds, of these pulses.

You cannot change the energy values that

are pulsed by configuring a setup
Parameters pulsed
register; you must change the links
between modules.

1
Once an I/O Expander port is in use by a Pulser module, the port is not
available to other modules. To make a port available, you must change
the Port setting of the module using the port to “NOT USED”.

Digital Input Framework
This sub-framework is located in the Advanced folder. This folder contains the
ION modules that control the behavior of the I/O Expander digital input
ports. Included in this folder are eight Digital Input modules, eight Counter
modules, two External Pulser modules, and two Pulse Merge modules.

The Counter modules are used to count the number of state changes
occurring in the Digital Input modules. The Pulser module, when pulsed,
resets the Counter modules to zero. Master Reset also resets the Counter
modules to zero.
The Digital Inputs are pre-configured to read pulses from the digital input
ports on the I/O Expander. Using Designer, right-click near the center of the
Digital Input modules to check the settings of the Port setup registers to ensure
the appropriate ports are in use.

Digital Outputs Framework

This sub-framework is located in the Advanced folder. This folder contains the
ION modules that control the behavior of the I/O Expander’s digital output
and analog output ports. Two areas in this folder are labeled “Form C
Relays” and “Form A Relays or Analog Outputs”.

Form C Relays
To configure the Form C relays, refer to “Energy Pulsing Setup” described
above.

Form A Relays
The Form A relays are controlled by the three Digital Output Modules and a
Pulser module.

By default, the Pulser module generates a pulse when the Sliding Window
(Rolling Block) Demand interval is reached. Set this Pulser module’s Port setup
register to an appropriate I/O Expander’s Form A port.

The three Digital Output modules are not linked to any parameters. Link an
ION module’s output to an input of the Digital Output. Set the Digital
Output’s Port setup register to an appropriate I/O Expander Form A digital
output. You may want to change the Digital Output’s Pulse Width setup
register.
