WARNING:

•Not a safeguarding device

•Failure to follow these instructions could result in serious injury or death.

• This device is not considered a safeguarding device because it just converts the signal from an

external device to an ISD compatible signal. A safeguarding or supplemental device with 2

normally closed (NC) contacts must be connected to this device. A safeguarding device limits or

eliminates an individual's exposure to a hazard without action by the individual or others. This

device cannot be substituted for required safeguarding. Refer to the applicable standards to

determine those requirements.

1.3 Overview

The SSA-ISD Connect with Indication is an adapter unit to integrate and serially connect Electromechanical Safety Switches

(EMSSs) without ISD into machine designs.

This connector can be used to connect a safety point on a machine that is not suitable for an existing ISD device, such as a

panel mount e-stop or mechanical interlocks on a door. The SSA-ISD Connect interfaces with devices that have two

normally closed (NC) safety contacts.

The indicators on the SSA-ISD Connect provide local diagnostics. One LED provides the status of the input device. The

other LED provides the status of the OSSD inputs (ISD chain).

2 Installation Instructions

2.1 Mechanical Installation

Install the SSA-ISD Connect to allow access for functional checks, maintenance, and service or replacement. Do not install

the SSA-ISD Connect in such a way to allow for intentional defeat.

All mounting hardware is supplied by the user. Fasteners must be of sufﬁcient strength to guard against breakage. Use of

permanent fasteners or locking hardware is recommended to prevent the loosening or displacement of the device. The

mounting hole (4.5 mm) in the SSA-ISD Connect accepts M4 (#6) hardware. See the ﬁgure below to help in determining the

minimum screw length.

12.9 mm

NUT

3.9 mm

3 mm * for minimum

engagement of

three threads

Screw Length (with screw head fitting in counterbore) = 12.9 mm + “X” mm + 3 mm

CAUTION: Do not overtighten the SSA-ISD Connect's mounting screw during installation. Overtightening

can affect the performance of the SSA-ISD Connect.

Important: It is the responsibility of the machine builder (user) to ensure the SSA-ISD Connect series

wiring/cabling is not easily manipulated by an operator to defeat the safety function(s), for example,

ensure the operator cannot remove a device from the chain.

2.2 Installation Requirements

The device is intended for indoor use only and must not be affected by environmental conditions. Do not expose the device

to excessive shocks and vibrations, otherwise the device may be deformed or damaged, causing malfunction or operation

failure.

Electrical installation must be made by qualiﬁed personnel 1and must comply with NEC (National Electrical Code), NFPA 79

or IEC/EN 60204-1, and all applicable local standards. It is not possible to give exact wiring instructions for a device that

interfaces to a multitude of machine control conﬁgurations. The following is general in nature; it is recommended to perform

a risk assessment to ensure appropriate application, interfacing/connection, and risk reduction (see ISO 12100 or ANSI

B11.0).

1A person who, by possession of a recognized degree or certiﬁcate of professional training, or who, by extensive knowledge, training and

experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work.

WARNING:

•Risk of electric shock

•Use extreme caution to avoid electrical shock. Serious injury or death could result.

• Always disconnect power from the safety system (for example, device, module, interfacing, etc.),

guarded machine, and/or the machine being controlled before making any connections or

replacing any component. Lockout/tagout procedures might be required. Refer to OSHA

29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy.

• Make no more connections to the device or system than are described in this manual. Electrical

installation and wiring must be made by a Qualiﬁed Person 2and must comply with the applicable

electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or

IEC 60204-1, and all applicable local standards and codes.

2.3 Protective (Safety) Stop Circuits

A protective (safety) stop allows for an orderly cessation of motion for safeguarding purposes, which results in a stop of

motion and removal of power from the Machine Primary Control Elements (MPCE) (assuming this does not create additional

hazards).

A protective stop circuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically

linked relays, which are monitored through External Device Monitoring (EDM) to detect certain failures, to prevent the loss of

the safety function. Such a circuit can be described as a "safe switching point".

Protective stop circuits are either single channel, which is a series connection of at least two normally open contacts, or

dual-channel, which is a separate connection of two normally open contacts. In either method, the safety function relies on

the use of redundant contacts to control a single hazard. If one contact fails On, the second contact arrests the hazards and

prevents the next cycle from occurring.

Interface the protective stop circuits so that the safety function cannot be suspended, overridden, or defeated, unless

accomplished in a manner of the same or greater degree of safety as the machine's safety related control system that

includes the SSA-ISD Connect.

An ISD compatible Banner Safety Controller, such as the SC10-2ro, provides a series connection of redundant contacts

that form protective stop circuits for use in either single-channel or dual-channel control.

2.4 Output Signal Switching Devices (OSSDs) and External Device

Monitoring (EDM)

The SSA-ISD Connect is able to detect faults on OSSD1 and OSSD2. These faults include short circuits to +24 V DC and 0

V, and between OSSD1 and OSSD2.

Both OSSD outputs must be connected to the machine control so that the machine's safety-related control system

interrupts the circuit or power to the machine primary control element(s) (MPCE), resulting in a non-hazardous condition.

Final switching devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.

Refer to the output speciﬁcations and these warnings before making OSSD output connections and interfacing the SSA-ISD

Connect to the machine.

WARNING:

•Interfacing both output signal switching devices (OSSD)

•Failure to follow these instructions could result in serious injury or death.

• Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES,

PC) between the safety module outputs and the master stop control element it switches such

that a failure causes a loss of the safety stop command or the failure allows the safety function to

be suspended, overridden, or defeated.

• Connect both OSSD outputs to the machine control so that the machine’s safety-related control

system interrupts the circuit to the machine primary control element(s), resulting in a non-

hazardous condition.

experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work.

WARNING:

•Interfacing OSSD Outputs to Machine Inputs

•Failure to properly interface the OSSD Outputs to the guarded machine could result in serious

injury or death.

• To ensure proper operation, the Banner device output parameters and machine input parameters

must be considered when interfacing the Banner device OSSD outputs to machine inputs. Design

the machine control circuitry so that the maximum load resistance value is not exceeded and the

maximum speciﬁed OSSD Off-state voltage does not result in an On condition.

External device monitoring (EDM) is a function used to monitor the state of the external, positively guided (mechanically

linked) machine control contacts (Final Switching Devives (FSD) and/or MPCEs). The SSA-ISD Connect does not include the

EDM function. As a result, the SSA-ISD Connect should be used with an external safety monitoring device that monitors the

status of the two SSA-ISD Connect OSSDs and is capable of providing the EDM function.

Examples of appropriate external safety monitoring devices include the Banner SC10-2ro Safety Controller.

WARNING:

•The SSA-ISD Connect does not have external device monitoring (EDM).

•If EDM is required for the application, it must be implemented in the external control.

2.4.1 Fault Tolerant Output Feature

Faults that do not immediately compromise the safe operation of the SSA-ISD Connect (for example safety output to

external potential, crosswire short safety output) result in a delayed switch-off of the safety outputs.

The safety outputs switch off when the error warning exceeds 20 minutes. In case of error warning, the SSA-ISD Connect

will ﬂash the ISD red LED.

Use this fault tolerance feature to run down the machinery in a controlled manner. After ﬁxing the fault, the error message is

conﬁrmed by a voltage reset. The safe outputs enable and allow a restart.

Faults that directly affect the safe operation of the SSA-ISD Connect will immediately cause a lockout condition and the

OSSDs will turn off.
