The Power Series is a state-of-the-art microprocessor-based Silicon Controlled Rectifier
(SCR) power controller intended for controlling industrial heaters. This product is based on
one package with several configurations that include single phase, three phase, and single
phase-multizone capabilities. Each package configuration has a specific current rating
depending on the number of phases switched. The switching capabilities include 65 to 250A
rms at 50°C from 24 to 600V~ depending on the configuration or model number selected. See
page 1.2 for additional information on the Power Series configuration options.

Single Phase
This configuration can be purchased with any or all the features available on the Power
Series. The only limitations are the features selected by the customer upon purchase. It has
the highest current rating of all configurations since it is only switching one phase of the ac
line. It is intended for resistive heaters, but can also be used on transformer connected loads
in the phase angle firing mode.
Three Phase, Two-Leg Configuration
This configuration is intended for zero cross firing into a stable resistive heater, i.e.,
nichrome element. Typically, a three phase, three-wire delta or ungrounded wye/star connected heater is most often used where only two of the three V~ line phases are switched.
The third phase is a direct connection through a bussbar on board the Power Series and is
controlled by the previous two phases. For this reason, a two-leg configuration should not be
used for three phase grounded wye/star connected heaters. (For heaters that are required to
be three phase grounded wye/star connected, see “Three Phase, Three-Leg Configuration”
section below.)
Because this configuration does not allow phase angle firing, it should not be used on
transformer coupled heaters and less stable resistance heaters such as silicon carbide,
molybdenum disilicide, carbon graphite, or tungsten lamp heaters. This may cause
premature heater failure or nuisance fuse blowing.
Heater current monitoring and kVA options are available with a three phase, two-leg configuration via the heater diagnostics option. Phase angle firing, including current limiting and
heater bakeout, is not available.
Three Phase, Three-Leg Configuration
There are two Power Series configurations that include six SCR control. All features are
available in these configurations.
The three-leg version is intended for phase angle firing into a transformer connected load or
direct connection to heating that requires soft start and/or current limiting.
The four-wire configuration is intended for zero cross firing into a four-wire wye connected
nichrome/resistive heater.
Single Phase, Multizone Configuration
This configuration is available in two and three single phase zones. Back-to-back SCRs are
used and all of the features of a single phase unit are available. (Note that there is only one
alarm relay and all zones in the controller must use the same control method.) This configuration is intended for applications with multiple command signals from independent control
zones. The multizone platform offers reduced panel space compared to using multiple single
phase power controllers.
Heater Diagnostics
Heater diagnostics is a key feature of the Power Series SCR power controller. Heater
diagnostics may include all or only some of the features that require heater current
monitoring, depending on the model selected. Heater current monitoring is only available
with heater diagnostics installed on the controller. The features dependent on heater current monitoring are heater bakeout, current limiting, heater current and kVA monitoring,
retransmit, and heater monitoring alarms such as open heater, heater out of tolerance, load
balance, and shorted SCR detection/error. Heater diagnostics must also be installed if you
need phase angle control with current limit.

Installation
Installation, Chapter 2Watlow Power Series I 2.1
2
The following two chapters will explain how to install the Power Series
controller. Watlow power controllers are thoroughly tested before leaving the
factory, so the Power Series controller is ready to install when you receive it.
Chapters 2 and 3 describe the steps required to install the Power Series
controller. Refer to Chapter 2 for mounting information and Chapter 3 for input,
power, and load wiring of the Power Series.
Before beginning installation, read through these chapters to gain an understanding of the entire installation. Consider the installation carefully. Plan the
power, load, and input signal wiring before mounting the Power Series. Also
consider the cabinet space, controller dimensions, wire bending radius, and airflow. Use good wiring practices to minimize electrical noise problems.
∫
WARNING:
To avoid potential electric
shock and other hazards,
all mounting and wiring
for the Power Series must
conform to the National
Electric Code (NEC) and
other locally applicable
codes.
Power Series Wire Bending Radius at Base Current and Ambient
Temperature Rating and Replacement Semiconductor Fuses
Minimum recommended wire sizes are based on the NEC 30°C ambient with not
more than three current carrying conductors in raceway or cable, while also
considering the Power Series 50°C enclosure temperature and semiconductor
fuse rating. Use copper conductors only.
The terminal lug wire range for all Power Series amperages is 350 MCM to 6
AWG. The recommended terminal torque is 180 in.-lbs. (20 Nm.). Refer to page
3.1 for torque guidelines.
NOTE: Ground must be
wired with the same size
wire as line and load
connections to a ground
of sufficient current
carrying capacity.
NOTE: Integral semiconductor fuses do not
qualify as branch circuit
protection.
NOTE: The Power Series controller must be mounted vertically. When multiple units are used in one cabinet, it is
best that they are mounted side-by-side when possible. If they are mounted one above the other, adequate spacing
and airflow must be provided. See Enclosure Guidelines on page 2.3.
For models N20 through F30:
1. Determine the panel location for mounting the Power Series controller and punch or drill holes for the
4 mounting screws per the drawing below. The mounting plate can be used as a template.
2. Attach the Power Series mounting plate using 4 screws (customer supplied, #10 screw minimum, 1/4
inch screw maximum).
3. Align the heads of the shoulder screws on the back of the Power Series heat sink with the key slots on
the mounting plate. Push the unit in, and then down until it snaps into place. Mounting is complete.
For F35 models:
F35 models are a bolt-down package. Drill and tap six holes per the above drawing for 1/4-inch 20 bolts.
Add a 9-in. clearance dimension to help develop the
chimney cooling effect. This
should be on the top and
bottom of the Power Series
mounting.

Enclosure Guidelines
The Power Series must be mounted in a suitable electrical enclosure. It must
have adequate wire bending space and cooling. The maximum ambient
temperature in the enclosure must not exceed 50°C (122°F) for name plate
rating. For other output ratings and enclosure ambient temperatures, see output
rating curves on pages 2.5 and 2.6.
To maintain the proper cooling, the enclosure must be large enough to dissipate
the heat generated by the Power Series, or there must be some form of active
cooling.
1.Air circulation — fans bring air into the bottom of the enclosure and louver
plates to allow the air to exit the top of the enclosure. Filters are not
recommended as they can become plugged and block air flow. To maintain
80 percent of the CFM of a fan, the outlet must be four times the area of the
fan inlet. Ensure that each Power Series is within an unobstructed
airstream.
2.Vortex coolers operate on compressed air and provide good cooling on a
sealed enclosure, but are noisy and consume a lot of air.
3.Cabinet air conditioners work well on sealed enclosures.
4.Heat pipe coolers work well on sealed enclosures, but do not provide as
much cooling as vortex coolers or air conditioners.
To determine how much cooling is required:
1. Determine the amperage load on the Power Series. Multiply the amperage by
1.2 and then by the number of phases controlled. This is the output power
dissipated by the SCRs in watts. Add the watts dissipated by the controller’s
power supply (21W) and multiply the total power in watts by 3.41 to get
BTUs per hour. Vortex coolers, heat pipe coolers, and air conditioner cooling are
rated in BTUs removed.
2. Add up the watts generated by other electronics in the enclosure and
multiply by 3.41 to get BTUs per hour.
3. Add up the total BTUs inside the enclosure and pick a cooling device that will
remove that amount of BTUs.
4. For fan cooled enclosures, enclosure and fan manufacturers usually have
free software programs and application notes to help size the fans for
enclosures. If necessary, contact the Application Engineers at Watlow
Controls for assistance.
Harsh Environment
The Power Series meets standards UL508, Pollution degree 3 for safety which
states: “Conductive pollution occurs or non-conductive pollution occurs which
becomes conductive due to condensation which is to be expected.” However,
Watlow recommends that the Power Series be used in a clean, dry environment
to ensure long-term reliability.
Page 10
2.4 I Watlow Power SeriesInstallation, Chapter 2
Removing the Power Series
Controller
1. To release the Power Series controller from the mounting plate, press in on
the release tab at the top of the mounting plate.
2. When the release tab is in, push up on the controller from the bottom to
release it from the mounting plate. Beware of sharp edges on the heat
sink when you push upward. This will take some force!
3. The F35 model does not use the standard mounting plate. See page 2.2 for
mounting instructions. To remove: reverse the mounting operation.
Maintaining the Power Series
•Cleaning: The heatsink fins must be kept clean for proper cooling and the
printed circuit board should be free of conductive residue condensation.
•Calibration: Not normally necessary. See pages 6.15-6.16 for data restore
and backup.
•Retorquing: See page 3.1 for torque guidelines.
•Software backup and refresh: Not necessary; see page A.7, Power Series
Backup.
NOTE: All Power Series controllers have been 100 percent tested before shipment. The
records of these tests are on file for recall if necessary.
Figure 2.4 — The F35 Power Series (right) is cooled with larger fans.

CAUTION:
You may want to use a
large screwdriver to
press in on the release
tab while you are pushing
on the controller to avoid
potential injury to your
hands.

Zero cross (also known as burst firing) provides even
output power with the lowest level of noise generation (RFI). Zero cross is the preferred method for
controlling a resistive load.
The controller determines when the ac sine wave
crosses the 0-volts point, then switches the load,
minimizing RFI.
Zero cross control is available for all Power Series
configurations.
Soft start and current limiting are not available
with zero cross control.

Figure 5.1a — Zero cross switching.
Fixed Time Base - Zero Cross
In the fixed time base control method, the selected
percentage power level output is generated over a
fixed time period (i.e. a fixed number of cycles),
regardless of power level selected. Resolution of operator selectable power may be more precise than the
fixed time base allows. Selected power output level is
rounded to the closest possible power output value in
full cycles as necessary.
Line voltage compensation is not used in the fixed
time base control method.

Variable Time Base - Zero Cross
In the variable time base control method, an optimal
ratio of cycles on to cycles off is used to generate the
desired power output. The number of cycles needed
to completely generate a desired power level is
variable in single cycle increments. Line voltage
compensation algorithms are used to adjust the
percentage power output while operating in this
mode. Variable time base operation gives the best
response time and resolution and provides for the
longest heater life.
In single cycle variable time base below 50 percent
power, the unit is never on for more than one consecutive full cycle. Above 50 percent power, the unit is
not off for more than one consecutive full cycle while
maintaining the proper output.
Line voltage compensation is active if selected; however, it can be disabled.
Setup Page:
• Enter the Setup Page by holding ±¬for 2 seconds.
• When the display reads [algo], press ® until [`Off]

DC Contactor - Zero Cross
DC contactor control mode is a specialized version of
zero cross control in which the analog control input
is always used and percentage power output is fixed
at 100 percent or 0 percent.
The off/on thresholds are 2.0V/3.5V for voltage
input; 5.0mA/8.0mA for current input. This means
the unit is off for an input voltage (current) of
2.0V(5.0mA) or lower, and 100% on for an input volt-
age (current) of 3.5V(8.0mA) or higher. Maximum
input voltage is 10.0V.
In contactor mode use a four second cycle time to
improve heater diagnostics operation.
Line voltage compensation is not used under dc contactor control, the output is either 100 percent on or
100 percent off.
Setup Page:
• Enter the Setup Page by holding ±¬for 2 seconds.
• When the display reads [algo], press ® until [`Off]
[`set] {Algo]
is displayed. Press ÓÎto select [cont] dc
contactor.
NOTE: Heater Tolerance, Heater Open and Load Balance
alarms do not work in DC Contactor control mode.
The phase angle control method gates a limited
portion of the line voltage cycle to the load based on
percentage power selected. Soft start is always
included when phase angle is selected.
Phase angle control may not be selected in a 3
phase, 2-leg system.
Line voltage compensation will be used to adjust the
percentage power output while operating in this
mode if selected.
Current limiting is a valid option with phase angle if
the unit is equipped with heater diagnostics.

Features, Chapter 5Watlow Power Series ■ 5.3
Soft Start
Soft start is a variation of phase angle control
executed on startup in which there is a gradual
increase in power until the final selected power output is reached. If soft start is selected, the system
will execute the soft start sequence each time a zone
starts active control. This happens at power-on and
on recovery from an alarm such as “Line Loss.” The
soft start time is the time it takes to achieve 100 percent power after a zone restart. The actual time may
be greater than the set time because of the resolution, but the actual time will never be less than the
set time. Rate = 100.0 ÷ time. The actual power
achieved is set by the temperature control input (see
Figure 5.3a and 5.4a).
NOTE: Soft start is intended to be used only
for slowly
increasing power on the initial power request.
Soft start is available in single phase and 3 phase, 3leg models only.
Soft start is always used in systems with phase angle
control mode selected unless
[soft] is set to [```0].

Maximum Rate of Change
The maximum rate of change is used during normal
operation of a phase angle controlled system (after
a soft start sequence ends) to cause large changes in
requested power to be implemented gradually. The
maximum rate of change of the power is defined as
the percentage of power change allowed every 0.1 second. This prevents a sudden increase or decrease in
current from one phase angle level to another level
from one cycle to the next into a nonlinear load that
could be damaged or blow a fuse.

Heater Bakeout
If a system is shut down for long periods, some
heaters can absorb moisture. With a standard power
controller, turning the power full “on” when moisture is present, can cause the fuses or the heater to
blow. However, with the Power Series you can now
“bake out” the moisture in a wet heater before
applying full power and destroying the heater.
During heater bakeout, the Power Series slowly
increases voltage to the heater while monitoring the
output current. If the heater achieves full output
before the bakeout time expires, then the heater is
dry and can be put into service. At all times, the output will not exceed the temperature controller set
point.
If the output current reaches a user-specified trip
point during the bakeout (as it would if arcing
occurred in the heater), then the Power Series shuts
off the output and activates an over-current trip
error, [HbOC]. The operator should then lengthen
the bakeout time and restart or just restart, depending on how long the initial bakeout ran. To start
heater bakeout you must cycle the controller power.
After a successful heater bakeout, the Power Series
automatically switches to the operator pre-selected
control mode (phase angle or zero cross).
NOTE: Heater bakeout is intended for magnesium oxide
filled nichrome elements. A nichrome element heater can
have a tolerance up to ± 10%. This tolerance could add to
the maximum heater current during normal operation. For
example, a 50-amp heater could draw 55 amps and still be
a good and dry heater.
Heater bakeout may be selected in single phase
(phase to neutral) and 3 phase, 6 SCR systems with
any pre-selected control mode. You must also have
the heater diagnostics option installed on your
Power Series.
Heater bakeout operates with an over-current trip.
The operator must set the maximum current
allowed during heater bakeout using the [HbOC]
prompt. This will set the maximum allowable load
during heater bakeout.

Heater Tolerance Detection
Heater tolerance detection allows you to detect a
failed heater or a heater that is beginning to fail. An
alarm is triggered if the load current drops below or
rises above specific levels.
For example, if you have five heaters that draw 20
amps each, for a total load current of 100 amps at
100 percent power, you could program the heater
tolerance alarm to trigger if the load current drops
below 80 amps at 100 percent power. This would
indicate that one of the heaters has failed (open.)
To monitor for a heater that is beginning to fail or
age, you could watch for too little or too much current. For example, in Figure 5.4b the alarm is programmed to trigger if the load current drops below 90
amps, or rises above 110 amps at 100 percent power.
The Power Series automatically adjusts the set
points, depending upon the percent power, as shown
in the illustration below.

Current Limiting
The current limit uses the RMS current entered by
the user. When a zone goes from 0.0% to a requested
power greater than 0.0%, the software increments the
output power by 0.1% increments per AC cycle until a
current limit is detected. The software will continue to
increment and decrement by 0.1% per AC cycle based
on the current limit until the goal power is met.
During normal operation (after the initial goal power
is met), a detected current limit will cause decrements
at 0.1% power per AC cycle until the current limit is
no longer active. The software will continue to increment and decrement by 0.1% per AC cycle based on
the current limit, until the goal power is again met.
Current limiting is available on units equipped with
heater diagnostics, (P _ _ 1 - _ _ _ _ - _ _ _ _ ).
Current limiting is not available with 3 phase, 2-leg
systems.
Current limiting is available under phase angle control operation.

Inductive Load Adjustment
The effect of inductive loads on current readings with
phase angle control can be factored in by requesting
an Inductive Load Factor Adjustment. This feature is
used to improve current measurement when phase
angle firing into a transformer or other inductive
loads.
The adjustment should be done with active phase
angle control with a requested power of 5% to 50% in
the zone of interest using a true RMS current meter.
NOTE: If an inductive load factor has been requested and
the load is no longer inductive, the current reading will not
be accurate. Use the [`Clr] parameter in the [Indf]
prompt to remove the inductive factor.

• Enter the Setup Page by holding
±¬

• When the display reads [algo], press Î until [Opt1]

[Indf]
Using the ÓÎkeys, select [`req] in the upper
display.
• Press ® until [1CuR] appears in the lower dis-
play. The upper display shows the current calculated by the system with no inductive factor.
Read the actual current measured by a true RMS
meter; use the ÓÎ keys until that value is
displayed.
• Press ¬ until [Indf] appears in the lower display. Using the ÓÎ keys, select [`ACt] in the
upper display. After 5 seconds, the prompt will
read [idle] if the adjustment was successful, or
[`Err] if there was an error.
• To return to using no Inductive Load Factor,
select [`Clr].
NOTE: Using the inductive load factor parameter the Power
Series displayed current can only be increased to match
the current reading of a true RMS meter. The Power Series
displayed current reading cannot be decreased below what
it initially calculated and displayed. The maximum inductive load factor increase allowed is 50% of the non-inductive current measured initially by the Power Series. If you
exceed the allowable adjustment then the Power Series
will display [`Err] in the upper display and [Indf] in
the lower display. In the event of an error push the up or
down key to [`req] and start the process over.
Page 28
Baseline Voltage and
Voltage Compensation
The baseline voltage is used by the controller to
adjust the output so that the system power remains
constant. This adjustment is called voltage compensation. The requested power is assumed to occur at
the baseline voltage. If there are any deviations of
the line voltage from the baseline voltage, the
applied output power will be adjusted.
For example, the starting line voltage of the system
is 121 volts and the baseline voltage is set to 121
volts. The requested power is set to 50.0 percent.
After the system has been controlling, the line voltage drops to 110 volts. During the time that the line
voltage is at 110 volts, the applied output power will
be adjusted to (121
2
/1102) x .50 = 60.5 percent so that
the system power remains constant.
The baseline voltage is also used for adjusting oper-
ating parameters in the software. It is important to
adjust the baseline voltage to the normal operating

Setup Page:
• Enter the Setup Page by holding ± ¬for 2 seconds.
• When the display reads [algo], press Î until [CTr1]
[`set][`set]
is displayed. Press ®
until [`nna] is displayed.
[``In]
Use the Ó Î keys to select either current {`nnA],

NOTE: Repeat this procedure for each zone that you wish to
configure.
Analog is typically 0-5VÎ (dc), 1-5VÎ (dc), 0-10VÎ
(dc), 4-20mA.
Digital is used for keypad manual control or
communications to control the Power Series.
Digital input is entered from the keypad in the
Display Loop on the [`1n1], [`1n2] or [`1n3]
prompt.
Current inputs are hardware limited to 0 to 20mA,
but may be scaled using the {nnA_] and {nnA–]
prompts. Note that the power will be fully off at the
current specified by prompt {nnA_] +.2mA, and
fully on at the current specified by prompt {nnA–]
-.2mA.
Voltage inputs are hardware limited to 0 to 10V, but
may be scaled using the {Uol_] and {Uol–]
prompts. Note that the power will be fully off at the
current specified by prompt {Uol_] +.1V, and fully
on at the current specified by prompt {Uol–] -.1V.

Features, Chapter 5Watlow Power Series ■ 5.7
Alarm Standard
If an alarm is configured as “standard” [`Std], the
alarm indicators only occur while the alarm is active.
The alarm indicators are the relay, which state is set in
Active Relay State [ALgc] as either energized on
alarm or de-energized on alarm, and the display, which
has an indicator LED in the upper display and the
descriptive prompt for the active alarm. When the
alarm becomes inactive (and no other alarms are
active) the alarm indicators are turned off.
Alarm Latched & Unlatching an Alarm
Indicator
If an alarm is configured as “latched” [`Lat], the
alarm indicators remain active until the user deactivates them. For a latched alarm, the descriptive
prompt on the display in the Display Loop
will read
[`Lat], and the user can switch to [UnLA], if the
alarm is cleared, to turn off the alarm indicators.
Once alarm indicators have been turned off, the
operator does not have to reconfigure an alarm as
latched.
Alarms
An alarm takes some action, usually notifying an
operator, when a control parameter leaves a defined
range. A user can configure how and when an alarm
is triggered and whether it turns off automatically
when the alarm condition is over. A description of
the alarms and errors, why they occur, and how to
troubleshoot them can be found on pages A.4 - A.7.
Setup Page:
• Enter the Setup Page holding ± ¬for 2 seconds.
• When the display reads [algo], press Î until [`alr]
[`set][`set]
is displayed.
Global Alarm Configuration
The Global Alarm Configuration [glbl] is used
when all of the alarms in the system are to be
configured in the same mode. If individual alarms
need to be set to different configurations, the Global
Alarm Configuration should be set to [`OFF].
Alarm Silencing
If an alarm is configured as “silenced” [`sIl], the
relay does not activate on the active alarm, although
the display indicators are still visible. When the
alarm becomes inactive (and no other alarms are
active) the display alarm indicators are turned off.
Alarm Latched and Silenced
If an alarm is configured as “latched and silenced”
[lasI], only the display alarm indicators are active
until the user deactivates them. The alarm displays
must be switched off once the alarm has been
cleared. See unlatching an alarm indicator above.
Active Relay State
For maximum flexibility, the Power Series controller
can generate alarms from the energized or de-energized state of the relay. Creating an alarm from the
de-energized state of the relay is the most reliable
method of alarm generation since a power loss or
any other control malfunction would cause an alarm.

5.8 ■ FeaturesWatlow Power Series
Overview
A Power Series controller can also be programmed
and monitored by connecting it with a personal
computer or programmable logic controller (PLC)
via serial communications. To use this communications option, a Power Series must be equipped with
an EIA/TIA 232/485 (P_ _ _ - _ _ _ _ - 1 _ _ _)
communications board.
To view or change controller settings with a personal computer, you need to run software that uses the
Modbus™ RTU protocol to read or write to registers
in the controller. See Chapter Six, Parameters, for
the Modbus registers. These registers contain the
parameter values that determine how the controller
will function and the values that reflect the current
input and output values of the system.
Parameters relating to communications appear in
the Comms Menu (Setup Page). Match the Baud
Rate [baud] to that of the computer and select an
Address [Addr] (1 to 247, default is 1).
The Power Series supports a maximum read of up to
32 registers. See appendix A.8 for Modbus registers.

Retransmit
Retransmitting Output Load Current or
Load Power
The retransmit feature allows an output to
retransmit an analog signal that can serve as an
input variable for another device such as a chart
recorder to document system performance over time.
To use the retransmit feature a Power Series must
be equipped with heater diagnostics and a universal
retransmit board (P_ _ 1 - _ _ _ _ - _ 1 _ _).
Setup Page:
• Enter the Setup Page by holding ± ¬for 2 seconds.
• When the display reads [algo], press Î until[retr]
[`set][`set]
is displayed. Press ® :
Select [`Cfg] to choose the type of output
retransmitted, mA [`nna] or volts [UOlt].
Select [type] to choose the type of information
that will be retransmitted.
[nOne] retransmit not active.
[`CUr] retransmits the load current of
selected phase [phas] or zone [2one] if it is a
multizone unit.
[`HUa] retransmits the load power of selected
zone [2one] in all models.
Select phase [phas] or zone [2one] to choose the
phase/zone that will represent your retransmit
signal. A three phase unit can only be single zone.
To scale the retransmit output signal, set the low
value load current or kVA to be retransmitted with
[Cur_] or [HUa_] and set the high value load current or kVA to be retransmitted with [Cur–] or
[HUa–]. For example, if you want 4-20mA to represent
a 50A to 250A current, set [Cur_] to 50 and [Cur–]
to 250. As the load current varies between 50 and
250A, the retransmit output will vary between 4mA
and 20mA.
Current outputs are hardware limited to 0 to 20mA,
but may be scaled using the {rt| C_] and {rt| C–]
prompts.
Voltage outputs are hardware limited to 0 to 10V,
but may be scaled using the {rt| U_] and {rt| U–]
prompts.

Checking and Replacing Fuses
Ensure that all high voltage power is off. Slide the fuse cover
down. Using an ohmmeter, measure the dc resistance of the fuse to
determine if it is open. (Typical dc resistance is less than 1 ohm.)
If fuse is open, replace it by removing the old fuse using a 1/2 inch
socket and a #3 Phillips screwdriver. Be careful not to drop washers off
the bolt or screw ends. If they have dropped into the case, shake them
out gently.
The bolt will have 2 washers. The bottom machine screw will have
2 or 3 washers, depending on the size of the SCR in the unit. It is
important that the washers are replaced in the exact order
in which they were removed. Take care installing the fuse so
that its orientation matches the image that is printed on the PC
board.
With the new Cooper Bussman fuse in the unit, torque the bolt to 44
inch-pounds and the screw as follows: For models PXX-F20X-XXXX
and PXX-N20X-XXXX torque to 26 in.-lbs. (2.93 Nm.). For models
PXX-F25X-XXXX, PXX-N25X-XXXX, PXX-F30X-XXXX, PXX-F35XXXXX, and PXX-N30X-XXXX, torque to 44 in.-lbs. (4.95 Nm.). Close
fuse cover. If unit was taken off the wall, observe all terminal torque
specs when reconnecting wires. Unit should now be ready to resume
operation. Reapply power to the controller and line/load terminals.

Power Series Backup
There are three prompts which allow the user to manipulate the
EEPROM contents: Backup Data Set, Default Data Set, and Restore
Data Set. Each of these prompts have a choice of [`all], [`sys],[2n`1], [2n`2], or [2n`3].
There are two sets of data stored in the controller; the first is the
User EEPROM and it is what is read on every power on. The
second is the Backup EEPROM.
The Default Data Set prompt will update the chosen configuration
parameters in the User EEPROM to values that are listed in the
manual as default. It will update the chosen input and retransmit
calibration parameters in the User EEPROM to the values that are
stored in the Backup EEPROM by the factory.
The Backup Data Set prompt will update the chosen configuration
parameters in the Backup EEPROM from the current values stored
in the User EEPROM. It will NOT overwrite the calibration
parameters.
The Restore Data Set prompt will update the chosen configuration
parameters in the User EEPROM from the current values stored in
the Backup EEPROM. It will NOT overwrite the calibration
parameters.
