General

There are three types of ATS (Automatic Transfer

Switch) Annunciators. They are identified as follows:

Catalog 214A400 Master Unit
Catalog 214A404 Master Unit

used with a Network Supervisor

Catalog 214A401 Slave Unit

Each installation must have a master unit; each
master unit can support two slave units. Each unit can
annunciate four ATSs. Therefore a master and two
slave units can annunciate up to twelve ATSs. To
annunciate more ATSs, additional masters and slaves
can be added.

ASCO Catalog 214A400, 214A404, and 214A401
ATS Annunciators are designed to provide remote
visual statusreporting and push buttontesting of ASCO
automatic transfer switches. Each ATS must have a
Group 1*, 5, 6, or 7 Microprocessor Controller with
Accessory 72A Serial Communication Interface Option
installed.

Serial Communications

Serial communications permits large amounts of information to be processed over a few wires. In the serial communications systems used by ASCO,each
individual device in the system --- automatic transfer switch, bypass-isolation switch, ATS annunciator, etc. --- has a unique code, or address, thatis
assigned to it through DIP switches in the devices. According to the established ASCO serial communications rules, or protocol, each ATS annunciator
and/or the network supervisor on the communication link “talks” to all automatic transfer switches and other elements being monitored on the link at
the same time. They all “hear” what is being said, but only the device that is addressed responds.

Sending and receiving requests and commands is done over the same pair of twisted wires linked in a network fashion from one device to another to form
the communication link, or highway. This physical configuration comprises a network in which only the addressed device is permitted to go on line and
respond to an inquiry. With this serial communications system, a minimum number of wires can be used to link the elements together. Without serial
communications,itwouldtakeconsiderablymorewirestoaccomplishthesamething.

INSTALLATION

The ATS Annunciator has been tested and is ready to use.
Installation simply requires mounting, connecting power
and communication wiring, and setting DIP switches. When
unpacking the unit, locate the loose partswhich are supplied
in a separate kit. The kits contain the following parts:

Master Kit 401091 Slave Kit 401092

label holder labels

& 2 resistors

label holder labels,

2 resistors, & ribbon cable

The Master ATS Annunciator can be readily identified by
the front mounted key switch (to prevent unauthorized
operation). You will find the key taped inside the back
panel. Up to two Slave ATS Annunciators can be mounted
directly above or below the Master. All t hree ATS Annun­ciators are then interconnected by means of ribbon cables.
All external wiring for power and serial communication line
connects to the Master ATS Annunciator. Observe the
requirements of the National Electrical Code (especially
Articles 725 and 800) and any local codes when interwiring.

Mounting

An Outline and Installation drawing (JS 387797) is included
in the back of this manual. The two---part enclosure, which
measures 10I wide x 6I high and 2I deep, is designed for
mounting to the standard wall boxes listed on the drawing.
After removing the front cover the hinged circuit board
opens to the right to expose the mounting holes in the base.

Loosen four screws to remove the cover as shown in Figure 1.
Rem ov e four screw s and remove the face plate. Then remove
the two left standoffs and swing the hinged circu it board to the
right as shown in Figu r e 2. You will find the key taped to the
back panel. Run the power wires (and insulated ground wire)
and comm un ic ation cable (twisted pairs) through the center
hole in the back of the enclosure, then to the right through the
notch in the circuit board. Attach the ATS Annunciator to the
wall box by using the mounting holes that line up. Swing the
circuit board closed again. R ein stal l the two standoffs and
tighten them securely. Reinstallthe face plate with four screws.

Connecting Slave ATS Annunciators

Connect the Slave ATS Annunciator(s), when used, to the
Master. Remove the adhesive labels from the slotted
openings as shown in Figure 2.

Then run the ribbon cable between ATS Annunciators and
plug each end into the adjacent sockets. Two Slaves may be
connected to one Master either by above and below
arrangement or two below arrangement. See the Outline
and Installation drawing for details.

INSTALLATION (continued)

Power Wiring

The Master ATS Annunciator can be powered by
either an ac or dc source (but not both) as shown on the
Outline and Installation drawing 387797 and in Figure

3. For ac wiring use a Class 2 bell transformer with a
120 V ac primary and a 16 V ac secondary (12 VA
minimum). Connect the ac wiring to terminals 9 and
10; connect the ground to terminal 1. For dc wiring
connect a 12 or 24 V dc power source (750 ma) to
t e r m i n a l s 7 ( --- ) a n d 8 ( + ) .

Communication Wiring

Connect one end of the transmit and receive commu­nication cable (twisted pairs) to terminals 3 through 6
on the Master ATS Annunciator as shown on the
Outline and Installation drawing 387797 and in Figure

3. Refer to the Daisy Chain and Star configuration
hook up drawings for typical arrangements. Use
communication cable specified in Figure 3. This cable
has two twisted pairs (4 wires) and an overall shield.
All twisted pair shields must be connected to terminal
2 for grounding. The earth ground is connected to
terminal 1 and internally jumpered to terminal 2. Two
resistors are supplied. Connect one resistor (390Ohm,
1/4 Watt, 5%) between terminals 5 and 6 on Master 1
only. See Figure 3. (The other resistor will be con­nected at the automatic transfer switch furthestaway.)
Two twisted pairs can be connected to the ATS
Annunciator terminal block. Use a separate terminal
block (not supplied) mounted in a separate wall box if
more connections are necessary, as shown in Figure 4.

Networks for Interconnecting ATS Annunciators and ATSs

Figure 3. Terminal block (Master).

Located on right side of circuit board.

Figure 4. Typical separate terminal block.

Refer to Drawing JS 401900 Sheets 1 through 4 for
typical interconnection schemes. The Daisy Chain
configuration utilizes a single run of communication
cable with all of the equipment connected in parallel as
shown on Sheet No. 1. This type of network utilizes the
least amount of cable and is probably the most popular
approach when long line runs are anticipated. Depend­ing on the desi red reliabili ty of the system, som e
consideration should be given to the effect of a cable
break. If the cable is broken all ATSs beyond the break
will lose their communication. It should be kept in
mind that annunciator lamps will flash if a disconnec­tion occurs. Also, a disconnection of the communica­tions cable will in no way impair the operation of the
automatic transfer switch.

Star networks can be used as an alternate configu­ration as shown on Sheet No. 2. With this approach,
greater reliability can be achieved because a discon­nect of the cable between the junction box and the ATS
will only impair one switch.

Depending on location of this equipment it may
sometimes be advantageous to use combinations of
Daisy Chain and Star networks. Typical configurations
are shown on Sheets No. 3 and 4.
