Introduction

The Recora Switchmat system is a pressure sensitive mat system designed for use as a
safety product in an industrial environment. The system provides the detection of a
presence in the protected work cell or perimeter.

Before installing your Recora Switchmat system, please read this information in full.
All installation procedures should be carried out by trained and qualified personnel and
should be in accordance with all safety regulations.

Presence sensing mats and controllers used to guard machinery and equipment are
regulated by government agencies, such as OSHA and ANSI. The responsibility of
compliance for a machine application, presence sensing mat and controller is in the hands
of the employer. The employer is responsible for proper installation, maintenance, and
training of users of safety devices. When a Recora presence-sensing mat and controller
are used to protect personnel from machinery or other hazards, it is the employers'
responsibility to meet all local, state, and federal regulations.

Warning!

The entire machine safety system must be tested at the start of every shift.
Machine testing should include proper machine operation and stopping
capability and verification of proper installation and settings of all operation
guards and devices before the operation is released for production.

Storage and Handling

Common caution is needed when unpacking and assembling the Recora Switchmat.

DO NOT drop the Switchmat, the edges and/or corners can be damaged

DO NOT use a sharp object when opening the shipping carton.

DO NOT pull the Switchmat using its lead wire(s).

The Switchmats should be stored in a vertical position. For larger Switchmats, two
people are required for safe lifting and to prevent damage to the switching element of the
mat.

System Description

Recora Switchmats are available in either a single or dual lead configuration, designated
as H for single lead and HD for dual lead. The type of series used should only be
determined after a risk assessment is performed. The level of safety protection required
for a given application is based on the risk associated with that application. The risk
associated with an operation is based on a number of factors that must be taken together
and evaluated in total to establish the risk level for any equipment or operation. It is

important to note that using a Switchmat alone will not make the installation a
safety system. A Switchmat monitoring controller must be used to complete the
safety system. When a 14HD (4-wire) series Switchmat is used together with the
FSC-6 mat controller, the safety system reaches a safety category 3 level. Safety

controls must have positive operation indicators; force guided relays, redundant critical
control components in order to meet the ANSI B11.19 guidelines.

The H series, a two-conductor lead cable, is used when a simple control function is
determined to be sufficient. The Switchmat requires low voltage; this is usually
accomplished by using a step-down transformer and a relay. The relay interfaces with
the supply voltage, acting as the on/off switches. The two conductors H Series should

not be considered in a safety application.

The HD series, a four-conductor lead cable, is usually required when the Switchmat is to
be used as a safety mat. The dual leads are necessary when used in conjunction with the
Recora Fail–Safe control unit.
