E-Stop Safety Module –
SECTION 4 – Electrical Hookup and Initial Checkout
It is not possible to give exact wiring instructions for a device such as the model
ES-TA-3F1 E-Stop Safety Module which interfaces to a multitude of machine control
configurations. The following guidelines are general in nature.
The E-Stop Safety Module has no delay function. The output relay contacts open within
25 milliseconds from the time that any Emergency Stop switch contact opens. This
classifies the E-Stop Safety Module as a functional "Category 0" Emergency Stop
control as defined by NFPA 79 (National Fire Protection Association Standard for
Industrial Machinery) and EN418 (European Standard: "Safety of Machinery,
Emergency Stop Equipment, Functional Aspects – Principles of Design").
4.1 Connection of Emergency Stop Switches
Connect the two poles of each Emergency Stop switch as shown in Figure 3. The
switches in Figure 3 are shown in their "ready" position with both contacts closed. See
Product Specifications on page 20 for E-stop switch input requirements.
NOTE: Jumper any unused inputs to simulate an emergency stop switch in the
closed-contact position.
4.2 Connection of Reset Switch
The circuit Reset switch can be any mechanical switch, such as a normally open
momentary switch, or a two-position key switch. The Reset switch must meet the
requirements listed in the Product Specifications on page 20. The Reset switch
connects between terminals 22 and 50 of the Safety Module.
The Reset switch must be located outside and not accessible from the area of
dangerous motion, and must be positioned so that any area of dangerous motion
may be observed by the switch operator during the Reset operation. Any areas not
in full view must use supplemental guarding to detect personnel.

or interlocking switch monitor. The use of
input devices other than emergency stop
switches (see section 2) may result in a
reduction in the safety category as
described by EN 954-1.
WARNING . . .
