INTRODUCTION
Thank you for choosing a Furman product and congratulations on your choice
of the ASD-120 2.0. The ASD-120 2.0 is a six channel power sequencing
device intended for use in installations where multiple electrical loads must be
powered on and off in a delayed and orderly sequence. Typical applications for
the ASD-120 2.0 include: touring PA or sound reinforcement systems, musical or
theatrical acts, mobile recording facilities, and on-location film or video shoots.
Essentially, any situation where AC power must be distributed to multiple circuits
and activated or deactivated in discrete stages would benefit from the use of an
ASD-120 2.0.
• All settings, options, and controls are now easily accessible from the front panel
• The output capacity of the 12V remote interface has been increased to 250mA
• Maximum sequencing delay has been increased to 7 minutes per stage
• The operation of the Remote interface has been harmonized with other Furman
products
• The Force Off warning is now highly visible
• The sequencing bypass switches are now low profile to prevent inadvertent
operation
• A security cover has been added to prevent unauthorized access.
• Rear rack mounting ears have been added to enhance road worthiness
Please read this manual completely and carefully and review the installation man-
• Phoenix-type connectors have been used to simplify installation
ual before installing or applying power to your ASD-120 2.0. Those familiar with
the ASD-120 will recognize that the ASD-120 2.0 provides the same functionality

IMPORTANT SAFETY INSTRUCTIONS
WARNING
• With the exception of input wire connections, there are no user serviceable
parts inside the ASD-120 2.0. The top panel should never be removed while
power is applied to the unit.
• Input power must be connected by a qualified electrician. The unit must be
properly grounded through a protective earth ground connection.
• Refer all servicing to qualified personnel. Servicing is required when the unit
has been damaged in any way or fails to operate as designed.
• The ASD-120 2.0 is intended for use in a dry environment. Do not use this
product in or near water. To reduce the risk of fire or electric shock, do not
expose this device to rain or moisture.
• The device is intended for AC power sequencing. All output circuits should be
sequenced OFF prior to removing power to the unit.
• Do not install this product near heat sources or other equipment that generates
excessive heat.
CAUTION
• The ASD-120 2.0 remote interface differs from the original ASD-120. While
the original ASD-120 REM terminal input was compatible with AC voltages, the
ASD-120 2.0 is not. For example, if an original ASD-120 is to be controlled by
the ASD-120 2.0, please use the Direct Current 12V and REM terminals of the
ASD-120 2.0 to provide the DC control signal to the REM input of the older ASD120 product.
• Ground loops at the control terminals and remote interface should be avoided.
The ASD-120 2.0 remote interface is designed to provide the flexibility of being
connected to multiple pieces of equipment within the same power distribution
system. To avoid ground loops, do not connect the remote interface to more than
one non-isolated ground referenced interface.
• A building’s AC Power Distribution System is grounded at the Utility Service
Entrance or Service Point. The ASD-120 2.0 Remote interface control is not intended for applications between multiple buildings or where connected equipment
has multiple AC grounds or earth paths. If the ASD-120 2.0 Remote interfaces are
connected to equipment grounded elsewhere, catastrophic voltage irregularities
can damage the remote interface. All control equipment interfacing the ASD120 2.0 power distribution network must be properly grounded through a single
protective earth ground connection. Please consult a qualified electrician if there
are questions concerning equipment grounding.

Prior to use, an appropriately sized power cable must be installed on the ASD120 2.0. A qualified electrician should be employed for selection of cabling and
installation. Bus bars for the connection of AC input power are accessible when
the top panel is removed. One safety ground terminal is also provided. The ASD120 2.0 is configured for 120/208 three phase power at time of shipment, but a
120/240V single phase source can be supported. Heavily loaded circuits can be
re-distributed between phases to balance the load as necessary.
The following instructions are provided as a guide for powering the ASD-120 2.0.
All steps should be performed while the unit is disconnected from power and
before it is installed in an equipment rack.
1. Determine the power source to be used with the ASD-120.
In North America, there are two possibilities: 120/208V three phase, and
120/240V single phase (sometimes called “Single Split”). Three Phase requires
an additional conductor, but it provides better copper utilization. A three phase
source will require five conductors; X (L1), Y (L2), Z (L3), N, and Safety GROUND.
The source must be a “Y” or “Wye” configuration and must include a star point
neutral. A 120/240V single phase source is connected with four conductors;
X (L1), Y (L2), N, and Safety GROUND. If the loads are balanced, the neutral current will be zero, but if the load is predominately on one phase, the neutral must
support the entire load current. Since phases are distributed to different circuits
a neutral conductor of the same gauge is the minimum recommendation,
a licensed electrician may recommend a thicker gauge neutral based on other
technical considerations.

2 1.5 W/ft 0.4 W/ft 2.3 W/ft 0.6 W/ft
Table 1 – Cable Loss Comparison
If the equipment is to be portable, a common connection method is to permanently attach a short cable whip to the Furman and terminate it with a high-current
connector. A long feeder cable with a mating connector would then be prepared
which could easily be disconnected for storage.
3. Prepare and connect the AC supply:
The AC supply cable will be connected to the internal bus bars via terminals that
secure the individual conductors with set screws. These terminals can accept
wires as large as 2 AWG. Strip one end of the cable to expose the wires. When
removing the outer jacket, be careful not to nick or cut into the insulation of the
individual conductors. When stripping the individual conductors, be careful not
to cut through any of the copper strands. All of the individual conductors should
be stripped one-half inch. After threading the cable end through the strain relief
clamp, connect the stripped conductors to the bus bar blocks. Be sure to put
each wire in the lower part of its terminal, so that it is compressed above and be-
low by copper rather than by the set screw itself. Tighten the set screws securely.
2. Select a cable and determine its length.
If the ASD-120 2.0 is installed in a permanent or semi-permanent location, it is
possible to connect it with flexible metal-jacketed conduit. A flexible type SOW
or SOOW supply cable known as a “whip” is recommended for portable use. In
three phase applications, the whip must carry a rating of 40 Amps minimum in
each of three out of five conductors; and for a single phase 120/240 source, a 60
Amp rated minimum for load current in two out of four conductors. The minimum
recommended conductor gauge is 6AWG for a 120/208 three phase source and
4AWG for a 120/240 single phase source.
Cable efficiency losses per foot are listed in Table 1. Losses are dramatically
reduced at lower currents since the losses are a function of the square of the
current. A larger cable size should be considered for critical loads that have high
peak currents, such as power amplifiers. Cable lengths can be longer if the load
current is significantly below the rated maximum, and if large transient peaks are
not expected.

4. Load Balancing:
The load should be balanced between phases. As shipped, the load circuits are
evenly divided among the X, Y, and Z bus bars in support of a balanced 120/208V
three phase input. If a 120/240 source is connected to the ASD-120 2.0, the Z
bus bar is not used and the load conductors connected to this bus bar must be
moved to the appropriate X and Y bus bars. (Please see Table 2.)
By default, there are two 12 AWG black conductors connected by Fast-On terminals to each bus bar. The black wires are labeled with a letter (A, B, C, D, E, or F)
corresponding to the circuit to which it is connected. Since the load is applied in
a sequence, the loads should be alternately applied to each phase as determined
by the position of the load phase conductors.
An example of how the loads should be connected is shown in Table 2.
An example of how the loads should be connected is shown in Table 2.
6. Next, terminate the source end of the cable:

Table 2. Load Balancing Example
To move a wire, grasp it by the terminal and pull straight up. Then re-position it
over an unused Fast-On male terminal on the appropriate bus bar and push down
firmly. Do not pull on the wires as this may compromise the integrity of the wire
crimp. If it is necessary to move load conductors, it will not be necessary to move
the smaller Phase LED indicator wires.
5. Tighten the cable strain relief clamp firmly:
At least one half inch of the outer jacket must extend beyond the clamp into the
interior of the unit. Replace the top cover. This completes the internal wiring of
the ASD-120 2.0.
REAR RACK EAR MOUNTING
The source end of the cable must be terminated by a qualified electrician
in accordance with national, local and municipal safety standards.
7. Optional 120V single phase source:
The ASD-120 2.0 can be powered from a 120VAC source, with the AC source
connected between the X and NEUT bus bar inputs, but the source current must
not exceed 60 amps and the maximum load must not exceed the source current.
The number of output circuits connected to the X bus bar must not exceed the
source current divided by 20A. For example, a 120 Volt 60 Amp feed will limit the
Furman ASD-120 2.0 to a capability of only (3) 20A breaker circuits, and therefore, only 3 internal load conductors are recommended. (Only three 20A circuits
will be operational and the other three 20A circuits must be defeated.)

PRODUCT OVERVIEW
The ASD-120 2.0 can be used as a stand-alone unit or in combination with other
Furman power distribution devices. The ASD-120 2.0 provides six sequenced
120V, 20A circuits for a total load power of 14.4kW. Higher levels of power
can be achieved by connecting additional Furman sequencers or other power
conditioning products, including additional ASD-120 2.0 units. Furman products
provide a practical means of centralized control over an extensive network of
power distribution and conditioning equipment.
As most sound reinforcement professionals know, AC power sequencing is necessary because the majority of equipment damage occurs when devices are either
powered up or powered down. In addition, power sequencing is needed whenever
various kinds of equipment must be powered up or down in discrete groups,
rather than simultaneously. Power sequencing allows equipment to be powered
up and powered down in an orderly and time-delayed sequence.
In professional audio, power sequencing is used to prevent speaker “pop” in
speaker cabinets, enclosures and line arrays. The “pop” is generated when audio
sources are switched on or off while an amplifier is still “live” or energized. The
activation of source (signal processing) equipment often creates a small spike of
transient voltage. When this voltage is amplified by the amplifiers, the resulting
“pop” can be deafening and can easily damage speaker voice-coils. The reverse
or “power down” of signal processing equipment can create a similar effect as
during power down many devices emit uncontrolled transients. Power down
transients can result in speaker “pop” and damage speaker components as well.
Because AC power sequencing prevents this universally unwanted and often
costly circumstance, AC power sequencing is prudent.
Power sequencing has the added benefit of preventing nuisance breaker trips by
offsetting the in-rush current demands of connected equipment over time. It is
not difficult to imagine the extreme current demand that would be placed upon a
breaker if all connected loads were to be activated at the same time. Power sequencing allows equipment to be sequenced on in discrete stages - which allows
each device to power up and current demands to stabilize individually. Although
each device will undergo its own in-rush current at power up, because these
events occur over time, the stress placed upon the breaker is greatly reduced.
For this reason, AC power sequencing is a reliable strategy for protecting event
productions and electrical infrastructure.
Years ago Furman introduced the original ASD-120, along with a full line of power
sequencers, to address the concerns outlined above. Furman power sequencing
products have been used by professional audio experts in a multitude of applications for decades. When conceiving the ASD-120 2.0, we listened intently to the
voice of our customers and industry experts. We appreciate all of the feedback
and believe that the ASD-120 2.0 delivers the power switching needs and wishes
of all of our customers.
The ASD-120 2.0 has a host of features and options that will be highlighted in
this manual.
Here is a quick overview:
The ASD-120 2.0 can be thought of as an array of six high current relays that operate under the control of a microprocessor. The six relays (referred to as DELAY
A through DELAY F) control the ON/OFF state of the power to six receptacles (also
referred to as DELAY A through DELAY F) located on the rear panel. The ON or
OFF state of each of the six receptacles is indicated by a series of six green status
LEDs on the front panel. There are a series of six circuit breakers located on the
front panel (underneath the status LEDs) that protect the loads connected to each
of the receptacles, DELAY A through DELAY F. Finally, there are a series of six low
power relays that operate in unison with the power switching relays. The contacts
of these low power relays are available on the right side of the rear panel and
allow the user to connect low voltage and low power devices to the ASD-120 2.0.
The ASD-120 2.0 has a rectangular security cover on the front panel. This cover
can be removed to provide access to an array of switches that are used to configure the operation of the ASD-120 2.0. Details of these switches can be found
later in this manual.
The basic operation of the ASD-120 2.0 can be described as follows:
Six individual Delay Banks feature a 120 Volt 20 Ampere AC circuit, and each AC
circuit can be sequenced on or off with a programmable delay at set intervals.
On/Off sequences can be initiated with ASD-120 2.0 front panel switches or a
wired connection to the ASD-120 2.0 rear panel Remote interface. Each Delay
Bank has one NEMA 5-20R duplex provided on the rear panel. In addition, any
Delay Bank can be configured as Always On or Always Off independent from the
sequence. The Delay Banks also have their own independent DC relay terminal
for triggering other devices, including another ASD-120 2.0 or any Furman
sequencing product.
The ASD-120 2.0 should be configured at time of installation. X Y Z Status LED
indicators confirm the input phase of AC power. The configuration DIP switches
are located behind a cover plate in the center of the front panel. A potentiometer
is used to set delay timing intervals. After the ASD-120 2.0 is configured, the
cover plate prevents inadvertent changes and tampering. A locking switch with a
removable key is provided for added security.

The ASD-120 2.0 Remote interface located at the rear panel provides a great
deal of flexibility. The ASD-120 2.0 can be configured to command or respond
to other controller-type equipment via low voltage DC impulses. If configured
as a remotely controlled power source, the ASD-120 2.0 can respond to
continuous maintained or momentary contact closures, open contacts, or the
presence or absence of external DC voltage. At the same time, maintained
control signals can be generated by the ASD-120 2.0 triggering connected
equipment into or out of operation. Low level DC relay contacts A through
F on each Delay Bank provide the means for external control of equipment
associated with each AC circuit Delay Bank.

FRONT PANEL CONFIGURATION & FEATURES
Installation is simplified by the unit’s 19 inch rack-mount design and hidden
rear rack-mount ears. This feature is found alongside an industry standard 2RU
chassis. The hidden rear mounts are adjustable.
Once installed and configured, you may expect years of trouble-free operation
from the ASD-120 2.0. If during the service life of the product a question or
issue may arise, please welcome our assistance and contact Furman. The unit
is backed by a three year manufacturer’s warranty detailed on page 22 of this
manual.
Note: The ASD-120 2.0 has no line cord or master breaker, and is designed to
be wired to a single phase 120/240V source with 60 amps per phase capacity, or
to a three phase 208 WYE source with at least 40 amps capacity per phase.
Start Sequence Button Switch
The Start Sequence button located on the left side of the front
panel can be used for sequencing power up or power down.
The “START SEQUENCE” button is only activated when the key
switch is set to the “Remote” mode. The function of this switch
depends on the position of DIP Switch 7 and the duration of time
that the button is depressed. Please note, setting the key switch
to ON defeats operation of the START SEQUENCE push button.
Both the key switch and the START SEQUENCE button operate in
either Maintained or Momentary mode.
Phase Indicators:
The ASD-120 2.0 features a set of three phase indicators; X, Y, and Z that will
illuminate green when the corresponding phase (X, Y, and Z) is receiving power.
These are sometimes referred to as “confidence indicators” because when these
lamps are illuminated, you can be confident that the ASD-120 2.0 is receiving
power. Although three indicators are provided, all three indicators will only be
illuminated when the unit is connected to 3-phase 208-WYE power. When using
240 split phase, only two of the only phase indicators (X and Y) will illuminate
Note: X Y Z Status LED indicators confirm AC power on each Input Phase.

The ASD-120 2.0 has six Delay Bank LED indicators that will illuminate green
when the corresponding Delay Bank (A through F) has been activated. When a
Delay Bank LED is OFF, the corresponding rear panel receptacle has not been
activated. When all Delay Banks have sequenced ON, all of the Delay Bank LEDs
should illuminate green. When all Delay Banks have sequenced OFF, all of the
Delay Bank LEDs should be off.
Note that the Delay Bank LED indicators only indicate when a bank has been
activated. The indicators do not guarantee that power is being delivered to the
corresponding Delay Bank. If a Delay Bank breaker has been tripped, the Delay
Bank LED indicator may still illuminate green even though power is not being
delivered to the Delay Bank with an open breaker.
The Delay Bank LED indicators are also used to indicate when the ASD-120 2.0
has been disabled due to a FORCE OFF condition. When the ASD-120 2.0 is in
FORCE OFF mode the Delay Bank LED indicators will flash on and off. More on
FORCE OFF mode later…
Note: A front panel Delay Bank LED indicator confirms the active state of the AC
duplex and its associated DC relay.

Security Cover Shield and DIP Switch Program Interface
The ASD-120 2.0 has six, 20 Amp thermal circuit breakers that protect each of
the six individual Delay Banks (A through F). The circuit breakers are located on
the front panel immediately below the Bank Status LEDs. Each of the six circuit
breakers (A through F) correspond to a Delay Bank (A through F)
If the combined current level plugged into a Delay Bank exceeds 20 Amps at any
time, the circuit breaker will “trip”, the circuit breaker button will pop outward, and
power will be cut to the devices connected to that particular Delay Bank.
If a breaker “trips” the user should review the load that is connected to the
offending Delay Bank and make adjustments as necessary to reduce load to
below 20A. To reset the breaker simply press the button in. Please note that
the breakers are thermally activated. It is best to wait a few minutes to allow the
breaker to cool before attempting to reset it.
Key Switch - 3 position ON/OFF Security Switch
The ASD-120 2.0 has a three position key switch that functions as a Local ON
Local OFF, and Remote interface selection switch. When the key is in the ON position, the ASD-120 2.0 will sequence all Delay Banks on and remain on. When
the key is in the OFF position, the ASD-120 2.0 will sequence all Delay Banks OFF
and remain off. When the key is in the REMOTE position the ASD-120 2.0 will
operate according to the signal presented at the remote interface and the action
of the front panel START SEQUENCE button.
If the key switch is in the REMOTE position and no signal is presented on the
rear panel Remote interface, the ASD-120 2.0 will operate according to the front
panel START SEQUENCE button. If the DELAY BANKS are off, pressing the START
SEQUENCE button will cause the DELAY BANKS to sequence on. If the DELAY
BANKS are on, pressing the START SEQUENCE button will cause the DELAY
BANKS to squence off. If the key switch is rotated from REMOTE to the ON or
OFF position, the ASD-120 2.0 will sequence ON or OFF according to the final
position of the key switch.
When the key switch is in the REMOTE position, the ASD-120 2.0 can accept on/
off commands from the rear panel 4-Pin Remote interface. The operation of the
remote interface is explained elsewhere in this manual. Please note that the ON
or OFF key switch positions defeat the rear panel remote interface.
REMOTE
ON: ON: Banks sequence ON and remain ON except
those configured as “ALWAYS OFF” with the bypass
OFF ON
switch.
OFF: Banks sequence OFF and remain OFF except those
configured as “ALWAYS ON” with the bypass switch.
The ASD-120 2.0 had two configuration DIP switches that are located underneath
a security cover near the center of the front panel. The two DIP switches are used
to set various sequencer options. You will need a small Philips screwdriver to
3
remove two 6-32
/8” Philips screws to gain access to these switches.
The ASD-120 2.0 comes with the security cover pre-installed to protect against
unauthorized configuration changes. The security cover is intended to discourage
unauthorized personnel from tampering with or adjusting set programming once
the unit has been installed. The security cover is attached to the front panel using
two 6-32 3/8” Philips head screws. Please use only the two screws provided for
attaching the security cover.
Note: Other types of tamper-resistant screws may be preferable depending on
the desired level of security. Please do not exeed the 3/8” length restriction.

The Sequence Bypass DIP Switches
ALWAYS OFF
The ASD-120 2.0 has a six-position, three-state DIP switch located under the
security cover on the front panel to the right of the multi – function DIP switch.
The sequence bypass switch is used to bypass the sequencing on any or all of the
DELAY BANKS. The sequence bypass switch is an array of six tri-state switches,
and each tri-state switch has three possible positions (ON. OFF, and SEQUENCE).
When the switch is set to the ON (“Always On”) position, the corresponding
DELAY BANK will be ON regardless of the state of the sequencer. When the switch
is set to the OFF (Always Off”) position, the corresponding DELAY BANK will be
OFF regardless of the state of the sequencer. When the switch is set to SEQ
(“Sequence”), the corresponding DELAY BANK will follow the state of the
sequencer.
Note that FORCE OFF mode has priority over the sequence bypass DIP switches.
When the ASD-120 2.0 is in FORCE OFF mode, all banks will be disabled regardless of the state of the sequence bypass DIP switches.
DIP position ON (A thru F) = Delay Bank and Relay is ALWAYS ON
DIP position SEQ (A thru F) = Delay Bank and Relay activates in Sequence

Note: Except for a Force Off condition, the Sequence Bypass DIP Switch
overrides any local or remote switch function.

The Multi-Function DIP Switch
1 2 3 4 5 6 7
The ASD-120 2.0 has a seven-position Multi-Function DIP switch array located
under the security cover on the front panel to the left of the bypass DIP switch.
The Multi-Function DIP switches are designated 1 through 7 from left to right and
a label for programming can be found on the inside of security cover plate.
This DIP switch is used to set the sequence delay time, active state of the FORCE
OFF feature, and program the behavior of the remote interface. The sequence
delay time is controlled by DIP positions 1, 2, and 3, FORCE OFF is controlled by
DIP position 4, and the remote interface behavior is controlled by DIP positions 5,
6 and 7. The DIP switch settings are ON when in the UP position and OFF when in
the DOWN position.
Note: The function of each switch is shown on a label located inside the F logo
cover plate.

DIP 4,
FORCE OFF Settings
DIP Switch position 4 is used to define how the ASD-120 2.0 will implement its
FORCE OFF feature. FORCE OFF is a safety feature that is designed to cut AC
power to all outlets instantaneously. Many municipalities require this feature as a
means of disabling equipment in the presence of fire or alarm. The FORCE OFF
inputs can be used with a momentary or maintained dry contact in either a Normally Open or Normally Closed state. The factory default position is DIP 4 ON or
UP, or (NO) Normally Open. In this configuration, the FORCE OFF will be triggered
when the FORCE OFF pins are shorted. If DIP Switch position #4 is on (DIP 4 OFF
or DOWN) the FORCE OFF pins must remain shorted for normal operation. In
this configuration, the FORCE OFF will be triggered when the short between the
FORCE OFF pins is removed.
If a FORCE OFF occurs, the power to all outputs will be immediately disabled and
the Delay Bank LEDs will blink together. To recover from a FORCE OFF condition,
the ASD-120 2.0 must be sequenced off locally, by turning the key swich to the
OFF position. Once reset, normal operations will resume. DIP 4 has priority over
DIP 5, DIP 6, and DIP 7 settings. Information on DIP 5, DIP 6, and DIP 7 can be
found in the following section.
The use of DIP 4 may or may not be a consideration for every install. By default,
DIP 4 is set to the ON (UP) position or (NO) Normally Open; meaning that the
ASD-120 will operate normally with an open circuit applied to the FORCE OFF input. In this default setting, shorting the FORCE OFF pins will cause the ASD-120
2.0 to go into FORCE OFF mode.
DIP 1, DIP 2, and DIP 3: DIP Time Adjustment
DIP switch positions 1, 2 and 3 and the position of the DLY ADJ (Delay Adjustment) pot control the time delay interval or “dwell time” between consecutive
stages when sequencing ON or OFF. The maximum time for each DIP switch is
shown inside the cover plate label and represents the delay time when the DLY
ADJ potentiometer is fully clockwise. DIP 1 adds 1 minute maximum time delay,
DIP 2 adds 2 minutes and DIP 3 adds 4 minutes. Please note these time delays
are cumulative. If all three DIP switches are in the UP position, the maximum
allowable time delay will be 7minutes, i.e. 1min+2min+4min=7min. The factory
default setting is DIP 1 ON or UP, and DIP 2 and 3 are OFF or DOWN. You can set
these switches in any position you like to achieve your preferred time delay.
Delay Adjustment (potentiometer)
DLY
ADJ
In order to precisely dial in your preferred sequence delay time, it is necessary
to set the Time Delay Adjustment (DLY ADJ) located left of the multi-function DIP
Switch. If this potentiometer is turned to its 100% value (fully clockwise), then the
time delay will be equal to the maximum time delay defined by DIP switches 1, 2,
and 3. If the potentiometer is in the 12 o’clock position (50%), then the time delay
will be 50% of the maximum time delay interval defined by the setting of DIP
Switch positions 1, 2 & 3. If all three DIP switches are off, and the potentiometer
is turned completely counter-clockwise, the time delay is minimal. The Time Delay
Adjustment potentiometer comes factory-set at 50%, the 12 o’clock position.
Example: If the DIP Switches are set to a 6 minute maximum delay and the potentiometer is set to its 50% setting, then the delay interval between sequenced
banks will be 3 minutes. (DIP 1 OFF or DOWN, DIP 2 and DIP 3 ON or UP = 6
minutes) x .50 = 3 minutes.
DIP 5, DIP 6 & DIP 7
Remote Mode Trigger Settings
DIP 5 (+12V, ON OFF) and DIP 6 (GND ON) are used in special situations, where
the factory-set remote options are not preferred. For instance, a newly remodeled
location has an existing remote key switch different from a Furman remote key
switch design, and it would be advantageous to use the existing key switch, since
many personnel already have keys. DIP 5 (+12V, ON OFF) and DIP 6 (GND ON)
could possibly address such situations. Please feel free to contact Furman, if
further assistance is necessary.
DIP 7 is used to set the remote switching preference. The ASD-120 2.0 can be
set to a Maintained Mode (DIP 7 OFF or DOWN) or a Momentary Mode (DIP 7
ON or UP) dependent upon the chosen method of remote switching. A Maintained switch method stays open until switched, and then remains closed until
switched again (such as toggle switches, e.g. Furman RS-1 key lock switch).The
Momentary switch method is normally open and stays closed only as long as the
button is depressed (such as pushbutton switches, similar to the Furman RS-2
security switch).
Momentary Mode does offer an advantage over Maintained Mode when multiple
remote switching locations are desired. Due to technical flexibility, Momentary
switching easily adapts when implemented with more than one remote switch.
However, maintained switching can be more stable, truly shunting control
voltages when actuated. DIP 5 and DIP 6 offer additional methods of applying
Maintained switching. Regardless of which switching method is chosen, when
changing DIP 4, DIP 5, DIP 6, or DIP 7, it is required to reset the Key Switch to
the OFF position before continuing the programming and installation.
9
The ASD-120 2.0 has one Momentary Mode of operation (DIP 7 ON or UP),
which is also compatible with Furman Legacy products. As suggested, when
more than one remote switching location is required, momentary switches offer
an advantage. In addition to this benefit, multiple Primary units set to Momentary
Mode can be interfaced together using the Remote Pole contacts +12V, REM and
GND, wired in parallel pole to pole. No one unit is considered the Primary Unit, yet
any unit can act as one. The multiple units’ delay cycle would initiate at the same
time, in combination with each other; in other words, the units would all start at
once and all initiate a cycle down at once, once any Momentary switch (button) is
pushed (including Remote Momentary switches). As mentioned, multiple momentary remote contacts should be used if more than one remote power up location
is desired. If units should drop out of sync, simply press and hold down the Start
Sequence button for several seconds to re-sync.
A front panel position DIP switch is used to set the sequence mode (+12V
ON, +12V OFF, GND ON, Mom/ Maint) which defines how the ASD-120 2.0 will
react to the signal presented on its REM input. The table below summarizes the
behavior which is described in further detail below. Note that DIP switch position
6 overrides the setting of DIP switch 5, and DIP switch 7 overrides switches 5
and 6.
DIP Switch position #5 (Factory default is OFF)
DIP Switch position #6 (Factory default is OFF)
DIP Switch position 6 defines how the ASD-120 2.0 will behave when GND is applied to the REM pin on the Remote interface. If this switch is in the ON position,
the ASD-120 2.0 will sequence ON when GND is applied to the REM input. If this
switch is in the OFF position the ASD-120 2.0will follow the behavior defined by
DIP Switch #5. DIP switch 7 must be in the OFF position (Maintained mode).
DIP Switch position #7 (Factory default is OFF)
DIP Switch position 7 defines the switching preference for switches or devices
connected to the REM pin on the Remote Interface. If this switch is in the ON
position, the ASD-120 2.0 will operate in Momentary mode. If this switch is in the
OFF position the product will operate in Maintained mode.
Maintained switches, for example toggle switches or push-ON / push-OFF push
button latching switches maintain their contact position until the switch is actuated a second time. Thus a switch that is closed will remain closed until the switch
position is changed (such as the Furman RS-1).
DIP Switch position 5 defines how the ASD-120 2.0 will behave when +12VDC is
applied to the REM pin on the Remote interface. If this switch is in the ON position, the ASD-120 2.0 will sequence ON when +12V is applied to the REM input.
If this switch is in the OFF position (+12V OFF) the ASD-120 2.0 will sequence
OFF when +12V is applied to the REM input. DIP switches 6 and 7 must be in
the OFF position (Maintained mode).

ASD-120 2.0 PROGRAMMING SUMMARY
Note: When programming a new configuration it is recommended to start with
the front panel Key Switch in the OFF position.
Multi-Function DIP Switch
• DIP 1 1M = 1 Minute Delay
• DIP 2 2M = 2 Minute Delay
• DIP 3 4M = 4 Minute Delay
Note: DIP 1, 2 and 3 sum together for a total sequence time of 35 minutes.
• DIP 4 N.O. / N.C. sets the active state of the FORCED OFF input
The factory default setting for FORCED OFF is “ON” or “normally open”. In this
mode, FORCE OFF is triggered when the FORCE OFF pins are shorted.
Note: If FORCED OFF mode is triggered ASD-120 2.0 will be disabled until
FORCE OFF state is cleared by resetting Key Switch to OFF.
Note: Force Off overrides the Sequence Bypass DIP Switch and all Delay Bank
LED indicators will flash.
• DIP 5 12VDC ON sets +12V Remote Mode
The factory default setting for 12VDC ON is “OFF” or disabled. If 12VDC ON is set
to ON, the ASD-120 2.0 will sequence ON if 12VDC is applied to the remote pin
on the remote interface.
12V OFF = 12VDC to REM deactivates
12V ON = 12VDC to REM activates
Note: Factory Default is MAINTAINED ON Mode with DIP 5 set down to 12V OFF.
• DIP 6 GROUND ON
The factory default setting for GND ON is “OFF”. If this switch is changed to the
“ON” position, the ASD-120 2.0 will sequence ON when GND is applied to the
remote pin on the remote interface.
REM to GND = ON
Note: To disable the front panel button completely, the GND ON Maintained Mode
should be used.
Note: GROUND ON mode overrides DIP 5.
• DIP 7 MOM / MNT - Momentary / Maintained
Sets local mode and remote contact closure preference for either Momentary or
Maintained switches.
Note: Momentary mode overrides DIP 5 and 6.
Sequence Bypass DIP Switch
• DIP position ON
(A thru F) = Delay Bank and Relay is ALWAYS ON
• DIP position SEQ
(A thru F) = Delay Bank and Relay activates in Sequence
• DIP position OFF
(A thru F) = Delay Bank and Relay is ALWAYS OFF
Note: Except for a Force Off condition, the Sequence Bypass DIP Switch
overrides any local or remote switch function.
Key Switch
• OFF = Banks sequence OFF except those configured as “ALWAYS ON” in the
sequence bypass DIP switch.
• REMOTE = Accepts On/Off signals through the rear panel REMOTE connector
and the Start Sequence button.
• ON = Banks sequence ON except those configured as “ALWAYS OFF” in the
sequence bypass DIP switch.
Note: The Start Sequence Button is disabled when DIP 6 is in GND ON mode
(Position UP).
Note: Loss of AC Power or utility interruption in Maintained Mode will result in all
Banks returning to the previous state when the utility service is restored. Maintained On, Banks will return to ON. Maintained OFF, Banks will return to OFF.
Note: Loss of AC Power or utility interruption in Momentary Mode will result in all
Banks returning to an OFF state when the utility service is restored.
Note: If switch #4 on the Multi-Function DIP switch is set to OFF (NC Mode) the
FORCE OFF pins on the rear panel must be shorted for normal operation.
In NC Mode, a FORCE OFF condition will be triggered if the FORCE OFF pins are
open circuit. The factory default is ON (NO Mode). In NO Mode, the ASD-120
2.0 functions normally with the FORCE OFF pins open circuit and FORCE OFF is
triggered when FORCE OFF pins are shorted.

REMOTE INTERFACE
The ASD-120 2.0 has a remote interface which can be used to control the ASD120 2.0 remotely using a Furman RS-1 (Maintained) or RS-2 (Momentary) wall
switches. In the most basic, single unit configuration, only two wires and a switch
are required to initiate a remote ON or OFF sequence. The switch may be either
a momentary or maintained-contact type. If a third & fourth wire are available, an
LED “Status Light” can be installed at the remote switching location to indicate
the status of the ASD-120 2.0. The pins on the remote interface are described
below:

PIN 1 +12VDC (12VDC Voltage Source)
The +12VDC terminal pin is a general purpose, 12VDC voltage source relative to
the GND (#4) pin. It is provided to allow the user to control the operation of the
sequencer by feeding the +12VDC signal back into the REM terminal input; which
is pin #3 on the same barrier strip.
PIN 2 STATUS (Output)
The STAT (status) terminal is an output that may be used to activate an LED to
indicate the status of the ASD-120 2.0. If the STAT terminal is high, the ASD-120
2.0 Delay outlets are either ON, or are in the process of sequencing ON. If the
STAT terminal is low, the ASD-120 2.0 Delay outlets are OFF. To use the STAT
terminal output simply connect an LED between the STAT and GND with the
Cathode (flat) side of the LED oriented toward the GND pin (Pin #4). Do not use a
series current limiting resistor. If the LED does not light when the remote switch
is ON, check the polarity of the LED and reverse the leads if necessary.
• If the LED is OFF, the DELAY outputs are OFF
• If the LED is ON, the DELAY outputs are ON
• If the LED is blinking, the DELAY 1, 2 or 3 outputs are in transition either from
ON to OFF or OFF to ON
PIN 3 REMOTE (Input)
The REM (remote) terminal is provided to allow remotely connected devices to sequence the ASD-120 2.0 ON or OFF. The ASD-120 2.0s’ REM terminal has been
designed to work with voltages from 5 to 30VDC. Filtering has been added to this
input to prevent false-triggering. The behavior of the ASD-120 2.0 is controlled
by the combination of the signal presented at the REM terminal input, and the
arrangement of the rear panel DIP switches. Please refer to FRONT PANEL DIP
SWITCH section (page 9) for more details.

ADVANCED INSTALLATION TOPICS
The beginning of the manual provides basic information for those who are familiar
with Furman equipment. A more complete description of ASD-120 2.0 operations
and configuration options are provided in the following sections.
Sequence Timing
Please note all Banks participate in the programmed time interval. The programmed delay time will cycle through all Banks A thru F, regardless of a Bank’s
assignment on the Bypass Switch. Banks that have been programmed as
ALWAYS ON, or ALWAYS OFF experience no effect in the program timing, since
bypassed Banks are independent of the ASD-120 2.0 control circuitry.
Note: The ASD-120 2.0 sequences each Delay Bank in order from A to F when
sequencing ON, and turn Banks F to A OFF in the reverse order when sequencing OFF. Triggers to initiate an ON or OFF sequence can occur at any time even
during a programmed sequence. If triggered to do so, a unit’s programmed
sequence will be and can be reversed at any time.
Sequence Initialization
Factory default mode for the ASD-120 2.0 is Maintained On. A sequence can occur at any time, reverse at any time, and/or FORCED OFF at any time, even while
a sequence is in progress. If Maintained Mode is configured and an SEQUENCE
ON trigger is received while the Banks are On, nothing will happen. The same is
true if all Delay Banks are OFF and a trigger to SEQUENCE OFF is received. Therefore if two or more remote switch locations are desired and the user would like
to sequence ON or OFF from both locations. Momentary Mode and Momentary
Switches must be employed. For example, if two Maintained switches are used
and the Multi-Function Set is configured in Maintained On mode, the ASD-120
2.0 will remain ON until both remote locations are set to OFF.
A time-delayed On or Off sequence can be initiated at the front panel Key Switch,
the START SEQUENCE button, or using the 4-Pin Remote Interface. The configuration Multi-Function DIP switches can program a sequence response utilizing
either Closed or Open Contacts, or the presence or absence of an external DC
voltage (5 to 30VDC max). The following basic examples of remote integration
are provided:

14
LOCAL AND REMOTE OPERATING MODES
Other configuration options are possible with an understanding of the REMOTE interface and configuration features of the ASD-120 2.0 discussed in the following
sections.
Key Switch Control
Secured local control of the ASD-120 2.0 is best accomplished by using the
front panel Key Switch. When in the ON position, all Delay Banks will sequence
ON, except those configured with the Bypass Set as Always OFF. All Banks not
configured as Always ON will be switched OFF once the Key Switch is returned to
the OFF position. If the Key Switch is intended to be the primary control method,
no external control connection to the rear panel REMOTE interface REM terminal
is recommended, and DIP 6 should be set to the GND ON position (DIP 6 UP). In
the absence of any external control signal, once the key switch has initially been
rotated to the ON position and returned to the REMOTE position, the ASD-120 2.0
defaults to ON in either Maintained Mode or Momentary Mode.
Note:: The front panel Key Switch must be in the REMOTE position for ASD-120
2.0 to accept remote commands. Furthermore, an ON or an OFF key position setting functions in either DIP 7 Maintained or Momentary mode effectively bypasses
all other command functions except the Bypass Set or a FORCE OFF condition.
Note: The Start Sequence Button is disabled when DIP 6 is in GND ON mode
(Position UP).
Note: Loss of AC Power or utility interruption in Maintained Mode will result in
all Banks returning to the previous programmed state when the utility service is
restored. Maintained On, Banks will return to ON. Maintained OFF, Banks will
return to OFF.
Note: Loss of AC Power or utility interruption in Momentary Mode will result in all
Banks returning to an OFF state when the utility service is restored.
Front Panel Start Sequence Button Control
The ASD-120 2.0 front panel Start Sequence button can be used as the primary
control to initiate a sequence. If the unit is programmed for Momentary Mode
(DIP 7 = ON), each time Start Sequence is depressed, the ASD-120 2.0 will toggle between ON and OFF sequences. If the button is pressed and held for more
than six seconds, the ASD-120 2.0 will sequence to the OFF state.
The front Start Sequence button should only be used when the Key Switch is in
the REMOTE position with DIP 7 the MOM/MNT dip switch set to MOM (DIP 7 in
the UP position).
Push buttons in multiple locations can be used to initiate ON/OFF sequences.
Remote control options are discussed in the Momentary Mode Section.
Note: The Start Sequence Button is disabled when DIP 6 is in GND ON mode
(Position UP).
Note: Loss of AC Power in Momentary Mode will result in all Banks returning to
an OFF state when the utility service is restored.
Remote Operating Modes
When the Key Switch is in the REMOTE position, the ASD-120 2.0 will respond as
configured by the switches behind the front panel cover plate. The ASD-120 2.0
can be programmed to respond to remote Momentary and sustained (Maintained)
trigger conditions. The unit can be triggered by the presence or absence of
contact closures or a DC voltage. The ASD-120 2.0 can also be used to trigger
remote equipment using the same type of trigger conditions.
The ASD-120 2.0 and similar equipment (available from FURMAN and other
sources) can be controlled in parallel with a control signal wired from a single
switch. Also, control connections can be made in series with various units triggered from an event occurring at another piece of equipment. An infinite variety
of connection schemes using any combination of these two methods is possible.
The momentary mode is only used with trigger signals that are of a short duration
such as a push button. Equipment compatible with this type of trigger can be
connected in a way that permits the initialization of a sequence from push buttons
in multiple locations.
Signal level relay contacts A thru F are provided at the rear panel of the ASD-120
2.0 which can be used for the purpose of triggering external equipment. The
contacts can be configured as a group as normally open (NO) or normally
closed (NC).
When the key switch is in either the ON or OFF position, the ASD-120’s sequencing circuits will not respond to the rear panel remote control inputs. If the key
switch is returned to the REMOTE position, the signals supplied to the rear panel
remote inputs will again control the unit.
15
Configuration for Remote Operation
Maintained switches are generally most convenient when there is only one remote
control location. The ASD-120 2.0 is shipped factory-set for Maintained On
operation. The alternate method of controlling the ASD-120 2.0 through the use
of a momentary push button switches can be used when more than one remote
switch location is required.
Note: The front panel Key Switch must be in the REMOTE position for ASD-120
2.0 to accept commands. Furthermore, an ON or an OFF key position functions
in either DIP 7 Maintained or Momentary mode bypassing all other program
functions except the Bypass Set or a Force Off condition.
Maintained On - 12V ON/OFF
When the Key Switch is in REMOTE mode, +12V present at the REM input with
respect to GND will initiate an ON or OFF sequence depending on the position
of DIP 5 (12V ON/12V OFF). After the sequence is complete, the output circuits
will remain in the configured state as long as +12V is present. The source of the
+12V can be from the remote interface itself, through remote relay contacts, or
can be supplied by a +12V source from connected equipment. The absence of
12V will cause the ASD-120 2.0 to toggle, and remain in the opposite state.
The ASD-120 2.0 cannot operate in the 12V ON/OFF Maintained Mode when DIP
6 is set to the GND ON mode. The GND ON switch will take priority. In 12V ON/
OFF Maintained Mode, one cannot use the START ON/OFF SEQUENCE button.
If someone does press the button, the ASD-120 2.0, if ON, will start an OFF
sequence that will last until you release the button.
Note: To disable the front panel button Start Sequence completely, the GND ON
Maintained Mode should be used.
Maintained On - GND ON
A simple connection from the REM terminal to the GND will initiate an ON sequence when DIP 6 is in the up position. After the sequence is complete,
the output circuits will remain in the configured state as long as the ground connection to REM is present. Opening this connection initiates the OFF sequence.
When DIP 6 is set for GND ON, the position of DIP 5 12V ON/OFF is ignored.
DIP #7 switch is set in the down position (MNT) for operation in Maintained
Mode. And when utilizing the REM and GND terminals, an ON response can be
programmed by setting DIP switches #5 and #6 accordingly. And when utilizing
the 12V and REM terminals, the same is true. The connection to the REMOTE
interface must exist, whether it be a presence or absence of 12V or open/closed
contacts. This mode is not typically used.
Note: The Start Sequence Button is disabled when DIP 6 is in GND ON mode
(Position UP).
Momentary Mode
In the Momentary Mode, a momentary switch such as the one located on the
front panel of the ASD-120 2.0, or the Furman RS-2 remote switch panel, can
be used to initiate an ON or OFF sequence. The Momentary Mode is selected
when DIP #7 (MOM/MNT) is in the up (MOM) position and DIP #6 (GND ON) is
in the down position. The position of DIP #5 (12V ON/12V OFF) is ignored. In
Momentary Mode, the ASD-120 2.0 will toggle between ON and OFF sequences
every time a trigger is received from the front panel button or at the REM terminal
with respect to GND. Multiple Furman devices with a REMOTE interface can be
synchronized by connecting the REM and GND terminals together.
When the ASD-120 2.0 has been configured for momentary mode, the REM
connection at the rear panel can act as an input or output depending on which
button is pressed. If the ASD-120 2.0 button has been pushed, the REM
connection provides a +12V output for as long as the button is depressed. Any
connected Furman products with REM and GND terminals will also cycle on or off.
To synchronize all equipment connected together in this way, press the START
SEQUENCE button for at least 6 seconds. The outputs of all connected products
will be shut off. If the connected product is a sequencer, the Sequence OFF will
be triggered. If remotely triggered, the sequence starts on the rising edge of the
signal at the REM terminal.
All Furman products connected in this way must be configured for Momentary
Mode. When first plugged in (or after power is lost and reapplied for any reason),
the ASD-120 2.0 outputs will remain off until a momentary trigger is received at
the REM input or the START SEQUENCE button is pressed. Pressing the START
SEQUENCE button while an ON or OFF sequence is in progress will result in an
immediate change in direction of the sequence.
Note: The Start Sequence button has no effect when thw ASD-120 2.0 is in
GND ON mode.
Maintained Off Mode
In the Maintained Off Mode, the ASD-120 2.0 will sequence ON or OFF with the
Key Switch or a remote activation trigger. In this mode the ASD-120 2.0 will
always remain in an OFF state until a connection is present between the REM
and GND terminals or between the 12V and REM terminals.
Note: Loss of AC Power in Momentary Mode will result in all Banks returning to
an OFF state when the utility service is restored.
16
STATUS Output
SIGNAL WIRE CONSIDERATIONS
The STATUS terminal is an output that may be used to illuminate an LED at
remote locations to indicate the ASD-120 2.0 has active Delay Banks. If it is high
(+12V), the unit is on (or at least in the process of sequencing on); if low, the unit
is off (or sequencing off). Simply connect the indicator LED between STATUS and
GND (a series resistor is not required). If the LED does not light when the switch
is in the ON position, check the polarity and reverse the LED leads. The STATUS
output is a 12V source, current limited to 10 mA. If you wish to generate a STATUS output voltage to a confidence monitor or an indicator, please use a 1k Ohm
1/4-watt resistor in series with the LED.
REMOTE Interface – Rear Panel 4 pin Connector
The four pin Remote Interface terminal strip on the back of the ASD-120 2.0
allows a switch (or parallel switches) to be connected to turn the unit on and off
from a distance. In the most basic configuration, only two Class 2 wires and an
SPST switch or relay contacts are needed to initiate an on or off sequence. The
switch may be either a momentary or maintained-contact type. An LED may also
be installed at the remote end to indicate when power is on, but this will require
a third wire.
DELAY OUTPUTS – Rear Panel 8 pin Connector
The DELAY OUTPUTS are a series of six isolated dry switch contacts that are
intended to interface with the end user’s low voltage power switching devices.
DELAY outputs A through F correspond to sequence stages A through F. The
N.C. (normally closed) and NO (normally open) relay contacts of all DELAY relays
are combined into two separate NO and NC switch buses which are brought out
to the rear panel DELAY Output interface. This allows the end user to select the
switching preference, either N.C. or NO, to be used for connected equipment.
The user may also connect either 12V or GND to the N.O. or N.C. switch contacts.
Furman recommends that control signal wires be 24 to 28 awg. this type of
wire is commonly available and works well. Generally, the choice is dependent
on the amount connected equipment to be utilized through any one of the three
interfaces REMOTE, DELAY OUTPUTS or FORCE OFF. Wire nuts may be required
in situations where many pieces of controlled equipment share the same pin.
Please note the low-voltage control signal must establish electrical continuity in
order to be reliable and craftsmanship is a must.
POWER DISTRIBUTION DESIGN CONSIDERATIONS
Furman is known for power distribution and surge protection, however it should
be noted the design of the new ASD-120 2.0 only provides surge protection on
its own internal components. There is neither surge protection on the Delay Bank
Duplex Outlets nor transient protection for the low-level DC contacts. Any conductor can provide a pathway for an electrical transient event, so all conductors
should be addressed when formulating strategies for surge protection. Please
call Furman for information and details on how system installs can be designed
for maximum protection from electrical transient events.
Note: A front panel Delay Bank LED indicator confirms the state of the DC relay
as well as its associated AC duplex.
FORCE OFF Interface – Rear Panel 2 pin Connector
The FORCE OFF input provides a method of immediately turning off all Bank
relays and output circuits. This input can be connected to a fire alarm panel to
disconnect power to all loads in the event of an emergency. DIP 4 behind the
front panel cover plate controls the trigger condition that forces the unit OFF.
All the Delay Bank LEDS will blink in unison if a FORCE OFF state is activated.
To reset the ASD-120 2.0, turn the Key Switch to the OFF position to clear
or if necessary, cede the service power to the ASD-120 2.0 to reset and clear.
Note: The ASD-120 2.0 is disabled when DIP 4 is set for (N.C.) mode. Factory
DIP 4 (N.O.) mode is recommended. Only a short across the Forced Off terminals
will activate the ASD-120 2.0 if DIP 4 is in the (N.C.) mode. This DIP setting is
reserved for alarm systems. Factory default for DIP 4 is (N.O) mode position UP.

ASD-120 2.0 PROGRAMMING SUMMARY
Note: When programming a new configuration it is recommended to start with
the front panel Key Switch in the OFF position.
Multi-Function DIP Switch
• DIP 1 1M = 1 Minute Delay
• DIP 2 2M = 2 Minute Delay
• DIP 3 4M = 4 Minute Delay
Note: DIP 1, 2 and 3 sum together for a total sequence time of 35 minutes.
• DIP 4 N.O. / N.C. sets the active state of the FORCED OFF input
The factory default setting for FORCED OFF is “ON” or “normally open”. In this
mode, FORCE OFF is triggered when the FORCE OFF pins are shorted.
Note: If FORCED OFF mode is triggered ASD-120 2.0 will be disabled until
FORCE OFF state is cleared by resetting Key Switch to OFF.
Note: Force Off overrides the Sequence Bypass DIP Switch and all Delay Bank
LED indicators will flash.
• DIP 5 12VDC ON sets +12V Remote Mode
The factory default setting for 12VDC ON is “OFF” or disabled. If 12VDC ON is set
to ON, the ASD-120 2.0 will sequence ON if 12VDC is applied to the remote pin
on the remote interface.
12V OFF = 12VDC to REM deactivates
12V ON = 12VDC to REM activates
Note: Factory Default is MAINTAINED ON Mode with DIP 5 set down to 12V OFF.
• DIP 6 GROUND ON / OFF
The factory default setting for GND ON is “OFF”. If this switch is changed to the
“ON” position, the ASD-120 2.0 will sequence ON when GND is applied to the
remote pin on the remote interface.
REM to GND= ON with Short
REM to GND, +5V to 30VDC at REM + DIP 5 12V OFF = OFF
REM to GND, +5V to 30VDC at REM + DIP 5 12V ON = ON
Note: To disable the front panel button completely, the GND ON Maintained Mode
should be used.
Note: GND to REM pins should be used for remote triggers with applied DC
voltages, +5V to 30VDC at REM.
• DIP 7 MOM / MNT - Maintained / Momentary
Sets local mode and remote contact closure preference for either Maintained or
Momentary switches.
Note: Momentary mode overrides DIP 5 and 6.
Sequence Bypass DIP Switch
• DIP position ON
(A thru F) = Delay Bank and Relay is ALWAYS ON
• DIP position SEQ
(A thru F) = Delay Bank and Relay activates in Sequence
• DIP position OFF
(A thru F) = Delay Bank and Relay is ALWAYS OFF
Note: Except for a Force Off condition, the Sequence Bypass DIP Switch
overrides any local or remote switch function.
Key Switch
• OFF = Banks sequence OFF except those configured as “ALWAYS ON” in the
sequence bypass DIP switch.
• REMOTE = Accepts On/Off signals through the rear panel REMOTE connector
and the Start Sequence button.
• ON = Banks sequence ON except those configured as “ALWAYS OFF” in the
sequence bypass DIP switch.
Note: The Start Sequence Button is disabled when DIP 6 is in GND ON mode
(Position UP).
Note: Loss of AC Power or utility interruption in Maintained Mode will result in all
Banks returning to the previous state when the utility service is restored. Maintained On, Banks will return to ON. Maintained OFF, Banks will return to OFF.
Note: Loss of AC Power or utility interruption in Momentary Mode will result in all
Banks returning to an OFF state when the utility service is restored.
Note: If switch #4 on the Multi-Function DIP switch is set to OFF (N.C. Mode) the
FORCE OFF pins on the rear panel must be shorted for normal operation.
In N.C. Mode, a FORCE OFF condition will be triggered if the FORCE OFF pins are
open circuit. The factory default is ON (N.O. Mode). In N.O. Mode, the ASD-120
2.0 functions normally with the FORCE OFF pins open circuit and FORCE OFF is
triggered when FORCE OFF pins are shorted.
