E-Stop Safety Module –
4.7 Connection to the Machine to be Controlled
The hookup diagram (Figure 3) shows a generic connection of the ES-TA-3F1 E-Stop
Safety Module's two redundant output circuits to Master Stop Control elements MSC1,
MSC2, MSC3 and MSC4. A Master Stop Control element is an electrically powered
device, external to the Safety Module, which stops the machinery being controlled by
immediate removal of electrical power to the machine and (when necessary) by
applying braking to dangerous motion (reference ANSI B11.19, section 5.2: "Stop
Control"). This stopping action must be accomplished by removing power to either
Master Stop Control element.
To satisfy the requirements of Safety Category 4 of prEN 954-1, the Master Stop
Control elements must offer a normally closed, force-guided monitor contact. One
normally closed monitor contact from each Master Stop Control element is wired to the
appropriate terminals on the module (see Figure 3). In operation, if any of the Master
Stop Control elements fails to de-energize, the associated monitor contact will remain
open. As a result, it will not be possible to reset the E-Stop Safety Module.
NOTE: If less than four MSC elements are controlled by the E-Stop Safety Module,
jumper the unused monitor inputs to simulate a closed contact. See NOTICE
Regarding MSC Monitor Hookup, at right.
Apply power to the machine control elements and perform the Periodic Checkout
Procedure (see section 5.2).
SECTION 5 – Operating Instructions
5.1 Security Protocol
The model ES-TA-3F1 E-Stop Safety Module should be mounted inside a lockable
enclosure. For security reasons, the key to the lockable enclosure must be in the
possession of a Qualified Person or Persons. A Qualified Person is a 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 (ANSI B30.2-1983).
The key to the Reset switch (if the Reset switch, as installed, requires a key) should be
available to a Designated Person or Persons. A Designated Person is one who is
identified and designated in writing, by the employer, as being appropriately trained and
qualified to perform a specified checkout procedure. A machine operator who meets
these requirements may be a Designated Person.

CAUTION . . .
Dangerous Voltage
Before performing the initial
checkout procedure, make
certain all power is disconnected from
the machine to be controlled. Dangerous
voltages may be present along the E-Stop
Safety Module wiring barriers whenever
power to the machine control elements is
"ON". Exercise extreme caution
whenever machine control power is or
may be present. Always disconnect
power to the machine control elements
before opening the enclosure housing of
the E-Stop Safety Module.
NOTICE Regarding
MSC Monitor Hookup
It is strongly recommended that one
normally closed auxiliary contact of
each Master Stop Control element
(MSC) be wired as an MSC monitor
contact, as shown in Figure 3. If this is
done, any inconsistency of action
between the MSCs will create a fault
condition, which will prevent the
E-Stop Module from resetting.
