Recora Neptune NF-2 Foot Switch - Manual (Page 4)

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.
