Section 1 GENERAL
Figure 1-1. PTR-1500
DESCRIPTION
The PTR-1500 is a communications system used for the protection of electric power generation and
distribution equipment. A protection system consists of two PTR-1500 units that communicate with each
other via voice-grade telecommunication lines (i.e., carrier, wire line or metallic pairs, fiber optics, and
microwave). The basic operation consists of a unit receiving a voltage from a closed contact (Trip input)
from a relay into the transmitting terminal and having it communicate to the receiving terminal, which
provides a closed contact and a externally sourced voltage output (Trip output).
FEATURES
DESIGN: The PTR-1500 has been optimized for high speed, high Dependability, and high Security. Single
and Dual Channel FSK modulation techniques are used in conjunction with digital differential Guard/Trip
energy sensing. These methods have a proven record of accomplishment for high reliability in the tone
protection relaying applications.
PROGRAMMABILITY: Operating characteristics of the PTR-1500 are controlled by firmware. The majority
of parameter changes are accomplished by changing DIP switch settings. A few logic changes are made
by PROM/EPROM replacement. Frequencies, channel bandwidths, communications protocols, and logic
modes are all programmable.
COMPATIBILTY: The PTR-1500 is compatible with other INIVEN PTR equipment as well as certain other
manufacturer’s audio tone protection equipment, depending on their configuration.
STABLE OPERATION: The Digital Signal Processing (DSP) technology used to generate the transmitter
frequency, establish receiver frequency discrimination, and manage all channel filtering, is crystal controlled.
This design provides a high level of stability, which overcomes the drift with temperature and age problem
encountered with analog methods.

LOGIC MODE OPTIONS
The PTR-1500 is designed as a four channel communications system that can operate in three different
modes depending on how the Logic module is programmed
1. DUAL CHANNEL – two frequencies are always generated by the Transmitter, either two Guard
tones or two Trip tones, one from Sub-Channel A and one from Sub-Channel B, from the selected
frequency Group (see Table 1-1) chosen by the customer. The Guard frequencies, one from each
Sub-Channel, are transmitted during normal, non-Trip, operation. When a Trip input is received by
the PTR-1500, the Transmitter will output both Trip frequencies, one from each Sub-Channel. The
PTR-1500 connected to the other end of the communication line will only allow a Trip output to the
receiving end’s relay when it has received both Trip signals simultaneously. The use of two frequencies
for Guard and Trip signals dramatically increases the Security (see Security charts later in this
section) of the system.
2. SINGLE CHANNEL – one frequency is generated by the Transmitter, either a Guard or Trip tone.
The frequencies will be either Sub-Channel A or B, but not both, of the selected frequency Group
(see Table 1-1) chosen by the customer. The Guard frequency is transmitted during normal, non-
Trip, operation. When a Trip input is received by the PTR-1500, the Transmitter will output the Trip
frequency and the PTR-1500 connected to the other end of the communication line will allow a Trip
output.
3. DUAL INDEPENDENT – two frequencies are generated by the Transmitter. The system operates
as two Single Channel units simultaneously. In this configuration, two separate Trip inputs are
received by the PTR-1500. Trip input 1 will be transmitted using a single frequency, Sub-Channel A
of a frequency Group (see Table 1-1) chosen by the customer. During normal, non-Trip, operation
the Transmitter will output the Sub-Channel A Guard tone. When a Trip input is received by the PTR-
1500 from Trip input 1, the Transmitter will output the Sub-Channel A Trip tone and the PTR-1500
connected to the other end of the communications line will allow a Trip 1 output. Trip input 2 will
cause the system to operate the Guard and Trip tones of Sub-Channel B in the same manner as
described for Trip input 1. Each Trip input will operate independently of the other.
Because the PTR-1500 is a four channel unit, it can operate 2 of the above logic schemes independently in
the same unit. The 2 “halves” of the unit need not be the same. For example, a PTR-1500 can be ordered
with 2 Dual Channels, a Dual Channel and a Single Channel, a Dual Independent and a Single Channel,
etc….
The PTR-1500 can also be ordered as a single direction or as the standard bi-direction. A single direction
unit can only transmit or receive while a bi-directional unit can do both. These options may also be combined
with the different logic configurations.

SYSTEM OPERATION
The following is a brief description of the standard modules that comprise a typical terminal. For detailed
descriptions, schematics and parts lists, refer to the individual module’s section in this manual.
POWER SUPPLY: Accepts the station battery voltage from the Line Interface module and produces a
regulated +5V output. It also isolates the rest of the PTR 1500 from the station battery.
LOSS OF POWER ALARM RELAY: A SPDT relay will be located on the Interface board, the wiring
connections are a 3 terminal board strip next to the power supply.
STATUS RELAY MODULE: Contains 8 relays that indicate problems with the communications system: 2-
Alarm, 2-Block, 4-LOS (Loss of Signal).
DC/DC MODULE: Contains overvoltage and undervoltage detectors that will disable the PTR-1500 Trip
circuits if the supply voltage is out of limit. The card produces ±12VDC outputs.
LOGIC MODULE: The PTR-1500 requires two Logic modules for quad channel operation. The Logic
module monitors all Trip inputs, furnishes all instructions to the tone Transmitter, analyzes the tone Receiver
outputs, and controls the Trip output drivers for one Dual Channel. The module also controls the Status
Relay module and monitors the DC/DC module. The Logic module utilizes a Z80 processor as its CPU.
LINE INTERFACE MODULE: Contains power supply filters, ON/OFF switch, and fuses. It also couples the
communication lines using four transformers.
MULTI-TRIP I/O MODULE: Contains five Trip input optical isolators and eight solid state outputs optically
isolated (4 - Trip and 4 - Guard).
TRANSMITTER MODULE: The PTR-1500 requires one Transmitter module (Quad-tone plus two pilot
tones). Utilizing the TMS320C16 DSP, the Transmitter performs calculations necessary to synthesize
required tone frequencies and to execute required control functions.
RECEIVER MODULE: The PTR-1500 requires two Receiver modules (two channels per Receiver module)
for quad channel operation. The Receiver utilizes the TMS320C16 DSP, which performs all calculations
necessary for tone filtering, control functions, and noise detection.

Section 2 INSTALLATION
This section of the manual covers installation, unpacking, mounting and interconnect wiring instructions.
UNPACKING
Various forms of the PTR-1500 may be supplied. The unit may be supplied as an individual chassis,
stacked interconnected chassis, or mounted in a rack or cabinet. Follow the procedure for the type of
system supplied.
INDIVIDUAL CHASSIS: An individual chassis will be packed in its own shipping carton. Inspect the carton
for possible damage in transit. Open each carton carefully and remove the chassis. Inspect the equipment
for possible damage. Verify all items of value have been removed from the carton prior to discarding the
packing material.
NOTE: It is suggested the carton be retained for possible onward shipment.
INTERCONNECTED CHASSIS: An interconnected chassis or equipment mounted in racks or cabinets
will be shipped either in special boxes (wood crates or via air-ride van without any case). Inspect the crate
or other packaging for possible damage in transit. Carefully remove the equipment from the container and
inspect it for damage. Verify all items of value have been removed from the crate prior to discarding any
packing material and refer to above note.
Should transit damage be found, please notify INIVEN immediately.
MOUNTING
INDIVIDUAL CHASSIS: Two screws are required per mounting bracket (four total per chassis) and are not
supplied with the unit. Install the chassis in the desired location and securely tighten all four screws.
Spacing of the mounting holes is compliant with EIA and DIN standards.
SYSTEMS: Systems provided in a rack or cabinet from the factory must be secured to the floor or wall as
required. Mounting hardware is not supplied due to the various surfaces and mounting methods.
CAUTION: EQUIPMENT MOUNTED IN SWING RACK TYPE CABINETS MUST BE SECURED TO
THE MOUNTING SURFACE PRIOR TO OPENING THE SWING RACK TO PREVENT THE CABINET
FROM FALLING.
INTERCONNECTED CHASSIS: Interconnected chassis’ or equipment mounted on shipping rails will be
mounted similarly to a single chassis. When shipping rails are provided, the equipment is to be placed near
the desired location. Remove the screws holding the shipping rails and remove them. Slide the equipment
into the rack or cabinet and secure it with the proper screws for mating hardware being used. Tighten all
screws.
NOTE: Adequate ventilation is required for reliable operation of electronic equipment. Temperatures within
the equipment room should be kept within specifications to assure reliable operation.
2-1

ELECTRICAL CONNECTIONS
User connections are made on the rear of the chassis through barrier and screw terminal blocks, fiber optic
connectors and the IRIG-B BNC connector, depending on the unit’s configuration. Not all types of connectors
are supplied on all PTR-1500 models. Refer to the end of this section or to the drawings that come with the
unit for specific wiring details.
References made to terminal blocks are via terminal block numbers. Terminal block TB-1 terminal 1 is
refered to as TB1-1. Terminal block TB-1 terminal 2 is refered to as TB1-2 and so on.
CAUTION: FOR SAFETY REASONS, ELECTRICAL POWER ON THE LEADS BEING CONNECTED
TO THE UNIT SHOULD BE DE-ENERGIZED DURING INSTALLATION.
Various methods of making the connections to the terminal blocks may be used and are based on local
practice. Lugs or bare wire may be used. Make sure to tighten all connections and insure exposed wires
and/or lugs do not touch each other or the chassis.
To reduce the possibility of induced currents on the Trip input leads, it is recommended that shielded
twisted pair wires are used with the shield grounded at the PTR-1500 end only. The Trip input leads and the
communication cables should be bundled separately from each other and the other leads.
TRIP INPUT: The Trip input current is limited to 10 ma. A resistor in series with the optical isolator on each
of the Trip inputs is used to limit the current. To produce a Trip, the battery voltage must be within 50% of the
input battery voltage.
TRIP & GUARD OUTPUT: Eight independent (Trip and Guard) outputs are provided with the standard
software. Outputs can be used singularly or can be used in parallel.
When an optional relay module is added, the interface board (see Section 5) may need to be modified.
Please consult the factory when changes to a PTR-1500’s factory configuration are being made.
STATUS RELAYS: There are eight status relay alarms each with a single set of SPDT (form C) contacts.
See Section 4-C. Status Relay, for status relay alarm functionality. All of the status relays are energized
during normal operation. Contacts are closed in their de-energized state.
AUDIO TONE LINES: The basic unit is supplied for four-wire operation. However, the Hybrid/Splitter module
(or similarly functioning module) can be configured for applications requiring two-wire communications.
GROUNDING THE EQUIPMENT IS IMPORTANT FOR BOTH SAFETY REASONS AND RELIABLE
OPERATION. Connect a 16 AWG or larger wire between chassis ground and earth ground utilizing the
shortest path to keep resistance and inductance to a minimum.
POWER CONNECTIONS: Verify the battery voltage matches the input power requirements of the
units.
WARNING: Double-check all connections for tightness and correctness, including polarity
as applicable. Replace all protective covers supplied.
