IronHorse GSDA-DP Digital Potentiometer General Information
The GSDA-DP digital potentiometer is a compact, microprocessor-based unit capable of being either
field or factory configured for a number of industrial user-interface / control signal needs. The GSDA-DP
allows the user to adjust the displayed value via the front-panel push buttons. As the displayed value is
raised or lowered, the output signal from the GSDA-DP follows proportionally according to the unit’s
configuration. These units support both unipolar and bipolar output and are capable of automatically
inverting, scaling, and offsetting the output as needed. The GSDA-DP series is ideal for volume OEM
applications requiring specialized inputs and outputs. This flexibility makes the GSDA-DP series ideal
for applications such as:
• Water and Waste Treatment Systems
• Conveyor Oven Controllers
• Synchronized Conveyor Lines
The GSDA-DP durable 1/8 DIN aluminum housings can be easily mounted in a panel or control cabinet.
A pluggable terminal block allows the installer to quickly install or replace units without the hassle of
physically removing and reattaching wires.
Carefully check the digital potentiometer for shipping damage. Report any
damage to the carrier immediately. Do not attempt to operate the digital
potentiometer if visible damage is evident to either the housing or to the
electronic components.

Basic Operating Information
The GSDA-DP digital potentiometer is a panel-mount digital-to-analog user interface. Put simply,
it allows the user to adjust the displayed value via push buttons on the front panel; and it outputs a
proportional signal according to its configuration. It can be configured to work with both single and
bidirectional partner drives. It also supports both unipolar and bipolar output supplies.
The GSDA-DP can display values in rate and time formats.
• In Rate mode, output units such as Gallons-per-Minutes, RPM, and Percent are possible with just a few
minor adjustments. (A set value of 200 will output twice as much voltage as a set value of 100.)
• In Time mode, output units such as Hours:Minutes (HH:MM), Minutes:Seconds (MM:SS), and
Seconds:Ticks (SS:TT) are supported. In Time modes, the output will be inversely proportional to the
displayed value in order to represent a programmable process time. (A set time of 1:20 will output twice
as much voltage as a set time of 2:40.)

Rate Mode Example: The GSDA-DP is wired to a +12 VDC Voltage Reference (Pot High supply). This
will control a drive that accepts a 12 VDC signal input. The driven motor has a rated speed of 1800 rpm.
For the operator to display/control the motor in rpm, set parameters as follows:
• P10 (Operating Mode) = 1 (Unipolar Rate Mode)
• P13 (Decimal point) = 3 (no decimal precision)
• P20 (Display Min Value) = 0
• P21 (Display Max Value) = 1800
• P25 (Output % Min) = 0

Time Mode Example: A conveyor transports product through an oven. At maximum speed, the conveyor
takes 90 seconds to send product through the oven. At the lowest desired speed (20% of max speed is the
slowest this conveyor should ever run), the conveyor takes 5 minutes to send product through the oven.
For the operator to control conveyor speed in minutes:seconds (cycle time) format, set the following:
• P12 (Display Zero Blanking) = 3 (show 3 characters)
• P13 (Decimal point) = 3 (no decimal precision) In time mode, the
display defaults to XX:XX without regard to this parameter setting.
• P20 (Display Min Value) = 90 (seconds)
• P21 (Display Max Value) = 300 (5 minutes, entered in seconds)
• P25 (Output % Min) = 200 (20%; P25 is entered in tenths of %)
• P26 (Output % Max) = 1000 (100%; P26 is entered in tenths of %)

Although the GSDA-DP user interface is very versatile, it is also simple to setup and operate. With just a
few button presses, it allows the user to configure a number of adjustable parameters. The LED display
has three basic operating modes: Running Mode, Parameter Selection Mode, and Parameter Entry Mode.
Each of the three modes have specific visual indicators that allow the user to immediately determine the
current state or mode of the user interface. Parameter Selection Mode and Parameter Entry Mode can
only be entered if the Program Enable jumper is in the “On” position.
Running Mode is the default display of the unit when power is applied. The GSDA-DP will spend the
majority of its time in this mode. In Running Mode, the display shows the target value in the appropriate
user-defined format of rate, time, or percentage. The control will continuously attempt to drive the motor
at the requested target rate. In this display mode, the Up and Down buttons increase or decrease the
displayed target value until either the display minimum or display maximum limit is reached. Depending
on the alarm configuration, these buttons may also serve as an alarm-silence or alarm-reset button.
Example displays for rate, time, and follower operating modes are 13.60, 45:30, and 9301.
Parameter Selection Mode can be entered by simply pressing and holding the Enter button down for three
seconds. Once in Parameter Selection Mode, the far left of the display will be a ‘P’. The right side of
the display will indicate the currently selected parameter number for editing purposes. Pressing the Up
or Down button will increase or decrease the selected parameter number on the display. Although the
parameter numbers are in numerical order, some numbers are skipped. These numbers represent reserved
parameters that are not yet implemented and are not displayed. Once the desired parameter number is
displayed, a press of the Enter button will change the display to the Parameter Entry Mode. When in
Parameter Selection Mode, pressing the Enter button with parameter 0 selected will cause the unit to
return to Running Mode. Example displays for Parameter Selection Mode are P 1, P 12, and P 54.
See the Software Parameters for a list of available parameters.
Parameter Entry Mode is used to modify the value of the selected parameter. When in Parameter Entry
Mode, the two dots which form the colon, between digits two and three, will alternately flash (one, then
the other) to inform the user that a parameter’s value is being edited. Pressing the Up or Down button
increases or decreases the selected parameter’s value. See the Software Parameters for a list of allowable
values and ranges. Value changes take effect immediately. For example, when scrolling through the
alarm output conditions, the relay will activate as the always-active selection is passed. Once the desired
value is showing in the display window, pressing the Enter button again will return to Parameter Selection
Mode. The new value is not saved in permanent memory until the Enter button is pressed. Removing
power from the unit while in Parameter Entry Mode may result in the specified new value being lost.
How to Change a Parameter’s Value
1) Hold down the Enter button until Parameter Selection Mode is entered.
2) Using the Up and Down buttons, select the desired parameter number to view or edit.
3) Press the Enter button to change the value of the parameter.
4) Using the Up and Down buttons, change the parameter’s value as desired.
5) Press the Enter button to permanently save the changes (Return to Parameter Selection Mode).
6) Select parameter zero and press the Enter button to return to Running Mode.

Parameter Descriptions (continued)
Parameter 10 – Operating Mode
This parameter defines the operating mode for the entire unit. There are two basic modes of
operation, Rate and Time. In Rate modes, the unit displays in rate and non-time-based units such
as RPM, Gallons per Hour, and Percent of Maximum Output. In Time modes, the unit displays
in time-based units using the format AA:BB. The AA:BB format can be adjusted to represent
Hours:Minutes or Minutes:Seconds.
• Mode 1 – Rate Mode, Unipolar Output
• Mode 2 – Rate Mode, Unipolar Output with Deadband
• Mode 3 – Rate Mode, Bipolar Output
• Mode 4 – Rate Mode, Bipolar Output with Deadband
• Mode 5 – Time Mode, Unipolar Output
• Mode 6 – Time Mode, Unipolar Output with Deadband
• Mode 7 – Time Mode, Bipolar Output
• Mode 8 – Time Mode, Bipolar Output with Deadband
• Mode 9 – Other Mode, Absolute Value Output with Relay Direction Control
This mode allows the GSDA-DP to interface with bi-directional Controls that have FWD and
REV command inputs and use the absolute value of the pot to determine speed only. In this
mode, the user must configure the following parameter:
• Display Min, Max, and Center
• Output Min and Max
• Output Deadband (Mode 10 Only!)
• Mode 10 – Other Mode, Absolute Value Output with Relay Direction Control and with Deadband
Function
Same as Mode 9, except deadband is supported. Must set Deadband value at Item 28.
Parameter 11 – Display Intensity
This parameter adjusts the intensity of the LED display digits in the front panel of the unit. The
values of 0 – 31 correspond to a gradual change from very dim to very bright. This is often useful
when the GSDA-DP is used in the same panel as other pieces of equipment with LED display and a
uniform display brightness is desired. Simply adjust the GSDA-DP to match its surroundings.
Parameter 12 – Display Zero Blanking
This selects the number of display digits that are required to be displayed regardless of the display
value. For example, with a Display Zero Blanking setting of 3 and a displayed value of 6, the
display would show “_006”.
• Mode 1: ___X – Always show at least 1 digit
• Mode 2: __XX – Always show at least 2 digits
• Mode 3: _XXX – Always show at least 3 digits
• Mode 4: XXXX – Always show all 4 digits
Parameter 13 – Decimal Point (DP) Position
This selects the format of the display with respect to the decimal point’s position. This parameter
does not affect the value entry for other parameters. The decimal point is only displayed in Rate
modes. For example, if the user desires to display numbers such as 12.34 or 1.05, then parameter 13
should be set to 2.
• Mode 0: Fixed XXXX (DP disabled)
• Mode 1: Fixed X.XXX
• Mode 2: Fixed XX.XX
• Mode 3: Fixed XXX.X
• Mode 4: Fixed XXXX.

Parameter Descriptions (continued)
Parameter 15 – Keypad Mode
This parameter selects the operating mode of the front-panel push buttons. In some applications,
increasing or decreasing the scroll rate provides the user more controllability when entering settings.
Parameters 14 and 15 affect only the Up and Down buttons when the user interface is in Running
Mode. These settings also apply to remote Up / Down buttons which are attached via the -1 option
board.
• Mode 1: Linear, Constant Rate
In linear mode, pressing and holding the Up or Down buttons will cause the display to
continuously change value in the requested direction until either the Display Minimum or
Display Maximum is reached. The displayed value will scroll at a constant rate which is
specified using parameter 16.
• Mode 2: Non-linear, Accelerating Rate
In non-linear mode, pressing and holding the Up or Down buttons will cause the display
to continuously change value in the requested direction until either the Display Minimum
or Display Maximum is reached. The displayed value will initially scroll at a slow rate and
increase in speed until the maximum scroll rate is achieved. The initial scroll rate is specified
using parameter 16.
Parameter 16 – Keypad Scroll Mode
This parameter sets the scroll speed for the front-panel push buttons. The function of this parameter
varies slightly depending on the Keypad Mode. See parameter 15 for more details.
Parameter 18 – Power-Up Mode
This parameter defines the mode which determines the default Running Value when power is
initially applied to the GSDA-DP.
• Mode 1: Default to Zero
When in this mode, the unit will default to zero (display units).
• Mode 2: Default to Power-Up Value
When in this mode, the unit will default to the Power-up Value, parameter 19.
• Mode 3: Default to Previously Running Value
When in this mode, the unit will default to the previous running value before power was
removed. A previous running value must have been active for at least 3 seconds to be recalled
after power has been disconnected and reapplied.
Parameter 19 – Power-Up Value
When Power-up Mode is set to 2, this parameter will designate the default display value at power-up
in display units.
Parameter 20 – Display Value at Minimum Output
This parameter defines the lower end of the display range. This is the value which limits how low
the user is able to scroll the displayed value in Running Mode. In Rate and Time modes, this value
is set in display units. This parameter is set without consideration for the decimal point’s position.
For example, setting this parameter to 125 would set the lower display limit at 12.5, 0.125, or 125
seconds according to the other configuration parameters.
Parameter 21 – Display Value at Maximum Output
This parameter defines the upper end of the display range. This is the value which limits how high
the user is able to scroll the displayed value in Running Mode. In Rate and Time modes, this value
is set in display units. This parameter is set without consideration for the decimal point’s position.
For example, setting this parameter to 1000 would set the upper display limit at 100.0, 1.000, or
1000 seconds according to the other configuration parameters.

Parameter Descriptions (continued)
Parameter 22 – Display Value at Center Output
This defines the center value for the display in bipolar (or bidirectional) modes of operation. In
bipolar applications, this value should be set to the display value that corresponds to a null or
zero output. When in Running Mode, display values above this will produce an output toward
the programmed Maximum Output %; whereas, display values below this will produce an output
toward the programmed Minimum Output %. As the display value approaches the number
programmed in this parameter, the GSDA-DP will produce an output that approaches the percentage
programmed in parameter 28. See parameters 25 – 27 for additional information.
Parameter 25 – Minimum Output % (in 1/10 percent units)
This parameter sets the output percentage which corresponds to the minimum display value,
parameter 20. This parameter has a range of 0 to 1000 which represents 0.0 to +100.0 percent of
output. When the user is adjusting the display value towards the programmed minimum display,
the output will linearly approach the value of this parameter. For example, setting this parameter
to 25 will configure the GSDA-DP to output 2.5% when the user adjusts the display value to equal
the display minimum, parameter 20. Setting this minimum percentage higher than the maximum
(parameter 26) will cause the polarity of the output to be inverted. See parameters 20 – 22 for
additional information.
Parameter 26 – Maximum Output % (in 1/10 percent units)
This parameter sets the output percentage which corresponds to the maximum display value,
parameter 21. This parameter has a range of 0 to 1000 which represents 0.0 to +100.0 percent of
output. When the user is adjusting the display value towards the programmed maximum display,
the output will linearly approach the value of this parameter. For example, setting this parameter to
850 will configure the GSDA-DP to output 85.0% when the user adjusts the display value to equal
the display maximum, parameter 21. Setting this maximum percentage lower than the minimum
(parameter 25) will cause the polarity of the output to be inverted. See parameters 20 – 22 for
additional information.
Parameter 27 – Center Output % (in 1/10 percent units)
This defines the center percentage for the output in bipolar (or bidirectional) modes of operation.
In bipolar applications, this value should be set to the percentage of output that corresponds to
a null or zero output of the partner drive. When in Running Mode, display values above the
display center (parameter 22) will produce an output toward the programmed Maximum Output
%; whereas, display values below the display center (parameter 22) will produce an output toward
the programmed Minimum Output %. As the display value approaches the programmed display
center value (parameter 22), the GSDA-DP will produce an output that approaches the percentage
programmed in this parameter. See parameters 20 – 22 for additional information.
Parameter 28 – Output Deadband % (in 1/10 percent units)
This defines the width of the output’s deadband. This is the range of output percentage values
which will produce a zero or center output percentage in unipolar and bipolar modes respectively.
This value is the width of the range in percentage units. For example: If the GSDA-DP were
configured for bipolar operation and this parameter were set to 50, then any output which was
within 5% of the center output percentage would be forced to the center output value. See
parameters 20 – 22 for additional information.

allowed to float disconnected, the output will once again correspond to the display value.
• Mode 2: Output 0% When S1 High
When the S1 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to 0%. Once the S1 input returns to an electrically low state or
wired to the unit’s common, the output will once again correspond to the display value.
• Mode 3: Output Setpoint When S1 Low
When the S1 input is at an electrically low state or wired to the unit’s common, the GSDA-DP
will force its output to a percentage which corresponds to the programmed jog setpoint,
parameter 31. Once the S1 input returns to an electrically high (+5V) state or allowed to float
disconnected, the output will once again correspond to the display value.
• Mode 4: Output Setpoint When S1 High
When the S1 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to a percentage which corresponds to the programmed jog
setpoint, parameter 31. Once the S1 input returns to an electrically low state or wired to the
unit’s common, the output will once again correspond to the display value.
• Mode 5: Output 100% When S1 Low
When the S1 input is at an electrically low state or wired to the unit’s common, the GSDA-DP
will force its output to 100%. Once the S1 input returns to an electrically high (+5V) state or
allowed to float disconnected, the output will once again correspond to the display value.
• Mode 6: Output 100% When S1 High
When the S1 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to 100%. Once the S1 input returns to an electrically low state or
wired to the unit’s common, the output will once again correspond to the display value.
Parameter 31 – Signal Input 1 (S1) Setpoint
When the S1 configuration, parameter 30, is set to one of the setpoint (jog) modes (modes 3 or 4),
this parameter defines the jog setpoint in display units. This parameter is always set in display units.

This parameter determines the operating mode of signal input 2 (S2).
• Mode 1: Output 0% When S2 Low
When the S2 input is at an electrically low state or wired to the unit’s common, the GSDA-DP
will force its output to 0%. Once the S2 input returns to an electrically high (+5V) state or
allowed to float disconnected, the output will once again correspond to the display value.
• Mode 2: Output 0% When S2 High
When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to 0%. Once the S2 input returns to an electrically low state or
wired to the unit’s common, the output will once again correspond to the display value.
• Mode 3: Output Setpoint When S2 Low
When the S2 input is at an electrically low state or wired to the unit’s common, the GSDA-DP
will force its output to a percentage which corresponds to the programmed jog setpoint,
parameter 36. Once the S2 input returns to an electrically high (+5V) state or allowed to float
disconnected, the output will once again correspond to the display value.
• Mode 4: Output Setpoint When S2 High
When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to a percentage which corresponds to the programmed jog
setpoint, parameter 36. Once the S2 input returns to an electrically low state or wired to the
unit’s common, the output will once again correspond to the display value.
• Mode 5: Output 100% When S2 Low
When the S2 input is at an electrically low state or wired to the unit’s common, the GSDA-DP
will force its output to 100%. Once the S2 input returns to an electrically high (+5V) state or
allowed to float disconnected, the output will once again correspond to the display value.
• Mode 6: Output 100% When S2 High
When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the
GSDA-DP will force its output to 100%. Once the S2 input returns to an electrically low state
or wired to the unit’s common, the output will once again correspond to the display value.
Parameter 36 – Signal Input 2 (S2) Setpoint
When the S2 configuration, parameter 35, is set to one of the setpoint (jog) modes (modes 3 or 4),
this parameter defines the jog setpoint in display units. This parameter is always set in display units.

Parameter Descriptions (continued)
Parameter 40 – Alarm 1 Conditions
This defines which conditions will result in the alarm 1 output being activated.
• Mode 0: Always Inactive
The alarm output will remain in an inactive state. In this state, the NC and C contacts will be
internally electrically connected.
• Mode 1: Always Active (When Power Is Applied)
The alarm output will become active when the power is applied to the unit. In this state, the
NO and C contacts will be internally electrically connected.
• Mode 2: Active When Display Value Above Limit
The alarm output will activate when the displayed value is above the upper limit setting,
parameter 48.
• Mode 3: Active When Display Value Below Limit
The alarm output will activate when the displayed value is below the lower limit setting,
parameter 47.
• Mode 4: Active When Display Value Inside Range
The alarm output will activate when the displayed value is greater than or equal to lower limit
settings and less than or equal to the upper limit setting.
• Mode 5: Active When Display Value Outside Range
The alarm output will activate when the displayed value is less than the lower limit setting or
greater than upper limit setting.
• Mode 6: Active When Display Value Results in a Zero or Equivalent Output
If the display is set to a value that produces a zero output or is within the programmed
deadband, then the alarm is activated.
• Mode 7: Relay Direction Control Mode
• In this mode, the relay output will determine which direction is being requested. This will typically be
used with Item 10 modes 9 & 10.
• Forward = relay not energized; Reverse = relay energized
Parameter 41 – Alarm 1 Output Style & Reset Configuration
This setting configures the output mode and reset method for the alarm output.
• Mode 1: Constant & Auto Reset
In this mode, the alarm output will remain active until the alarm condition ceases to exist. The
alarm will automatically reset when the conditions return to normal.
• Mode 2: Constant & Manual Reset
In this mode, the alarm output will remain active until the alarm is reset manually. See
parameter 42 for details.
• Mode 3: Pulse & Auto Reset
In this mode, the alarm output will pulse on and off until the alarm condition ceases to exist.
The pulsed modes are commonly used for audible alarms where a constant output would be
considered distracting or awkward. The alarm will automatically reset when the conditions
return to normal.
• Mode 4: Pulse & Manual Reset
In this mode, the alarm output will pulse on and off until the alarm is reset manually. See
parameter 42 for reset details. The pulsed modes are commonly used for audible alarms where
a constant output would be considered distracting or awkward.

Parameter Descriptions (continued)
Parameter 42 – Alarm 1 Reset Configuration
This setting determines which actions will cause an active alarm to be silenced or reset.
• Mode 1: No Silencing, Reset On Any Button Press
In this mode, an active alarm cannot be silenced. Once the alarm condition ceases to exist,
however, any user-interface button may be pressed to cause a manual reset.
• Mode 2: N
o Silencing, Reset On S2 Input High (Not Wired To Common)
Similar to Mode 1. Once the alarm condition ceases to exist, setting the S2 input to a high
(+5V) state or allowing it to float disconnected will cause a manual reset.
• Mode 3: No Silencing, Reset On S2 Input Low (Wired To Common)
Similar to Mode 1. Once the alarm condition ceases to exist, setting the S2 input to a low
(COM) state or wiring it to common will cause a manual reset.
• Mode 4: Silencing Enabled, Reset On Any Button Press
When the conditions for an active alarm persist, pressing any user-interface button will result
in the alarm being silenced or deactivated, but not reset. A second attempt to reset the alarm
must be made after the condition cease to exist to clear the alarm.
• Mode 5: Silencing Enabled, Reset On S2 Input High (Not Wired To Common)
Similar to Mode 4. Setting the S2 input to a high (+5V) state or allowing it to float
disconnected will cause the alarm to be silenced or reset depending on the current state of the
alarm conditions.
• Mode 6: Silencing Enabled, Reset On S2 Input Low (Wired To Common)
Similar to Mode 4. Setting the S2 input to a low (COM) state or wiring it to common will cause
the alarm to be silenced or reset depending on the current state of the alarm conditions.
Parameter 43 – Alarm 1 Display Flash On Alarm
This will cause the display to flash when an alarm condition is active.
Parameter 44 – Alarm 1 Pulse on Time
This parameter defines the number of seconds the output should be enabled during the ‘on’ phase of
an active pulsing alarm’s output.
Parameter 45 – Alarm 1 Pulse off Time
This parameter defines the number of seconds the output should be disabled during the ‘off’ phase
of an active pulsing alarm’s output.
Parameter 46 – Alarm 1 Pulse Count
This setting determines how many pulses are output when the alarm is activated and is configured
in pulse output style. When 0 is entered, the unit will be set for continuous pulses while the alarm is
active.
Parameter 47 – Alarm 1 Lower Limit
This setting defines either the lower limit or lower end of a range for the alarm region. Alarm limits
are set in display units without regard to decimal point or colon position. In Rate Modes, a limit of
123 could represent a display value of 123, 12.3, 1.23, or 0.123. When in Time Mode, a limit of 123
would represent 1:23 on the display.
Parameter 48 – Alarm 1 Upper Limit
This setting defines either the upper limit or upper end of a range for the alarm region. Alarm limits
are set in display units without regard to decimal point or colon position. In Rate Mode, a limit of
123 could represent a display value of 123, 12.3, 1.23, or 0.123. When in Time Mode, a limit of 123
would represent 1:23 on the display.

Parameter Descriptions (continued)
Parameter 95 – Factory Default Command
When set to a value of 5, the unit will be reset to factory default settings. This can also be achieved
by applying power to the unit with both the Enter and Down buttons depressed. The programming
jumper must be in the “On” position for this method to function.
Parameter 98 – Save to User Default Area Command
When set to a value of 1, the unit will store all adjustable parameters to the user default area. The
user default area is intended to be a location where an OEM or integrator can store settings specific
to their application. Using this, an OEM can easily refresh their custom settings in the field if an
end-user accidentally reconfigures the unit unsuccessfully. Another common use for this area is
testing and initial setup. The user can store known-good settings here and easily experiment without
the fear of losing the optimal configuration.
Parameter 99 – Restore from User Default Area Command
When set to a value of 1, the unit will restore all adjustable parameters from the user default area.
See parameter 98 for additional information.
Troubleshooting
If a newly installed GSDA-DP will not operate, it is likely that a terminal connection is loose. Check
the terminal connections and ensure that they are secure and correct. If the digital potentiometer is still
inoperative, refer to the Troubleshooting Table.
Troubleshooting
Problem
Possible Cause(s)
Corrective Action
Display is blank
1) Power not applied
2) Defective unit
1) Using a volt meter, verify that a voltage between 85 and 265 VAC is
measured between the L and N terminal block positions.
2) Contact AutomationDirect “Product Returns” for replacement.
Display is dim
Display intensity parameter
is too low
Editing and increasing the display intensity parameter should cause the display
digits to become brighter.
When power is applied,
“LF-L” is displayed
1) AC line supplying power
to unit has too much
noise
1) Review routing of power wires in machine to minimize electrical noise.
Look for other devices which share the same circuit which may be
producing unacceptable levels of line noise. In some applications, such
as welding equipment, a careful regiment of applying an AC line filter,
re-routine wires, dividing circuits, using shielded cable, and properly
grounding devices will usually solve the problem.
2) The unit is designed to operate with AC lines from 48-62 Hz (cycles
per second). This is typically not a problem because the international
standards are 50 and 60 Hz
2) AC line supplying power
to unit has an abnormally
low frequency
When power is applied,
“LF-H” is displayed
1) AC line supplying power
to unit has too much
noise
2) AC line supplying power
to unit has an abnormally
high frequency
The alarm output does
not seem to function

Alarm output parameters not configured properly
Review alarm output parameters. The alarm relay output can be tested by
selecting the “Always On” value for the Activation Condition parameters for
the alarm output. When doing this, the relay click should be audible and the
NC (Normally Closed) and C (Common) terminals should become internally
shorted at the terminal block.
