E-Stop Safety Relay
– Model ES-TA-3D1
4.3 Setting the MAC ID Address
In order for the DeviceNet controller to process information from its individual inputs,
each input must have a unique 2-digit address. (For example, two devices on the
same bus network may not both have 26 as their address; however, two devices
within the same factory may have addresses of 26, if they are on separate bus
networks.)
The ES-TA-3D1’s address may be assigned in two ways: locally, using the two rotary
selectors on the front of the module (see Figure 5), or remotely, using the rotary
selectors and the DeviceNet controller. To set the address locally, set the rotary
selectors to a number between 00 and 63 and cycle power to the DeviceNet
connection. To allow the DeviceNet controller to set the address, set the rotary
selectors to a number higher than 63; the address can then be set using the
controller.
The MAC ID LED will be off when the MAC ID address rotary switches match the
current address of the ES-TA-3D1 (as recognized by the DeviceNet controller). If the
addresses do not agree, the LED will flash. (To correct this problem, see DeviceNet
Troubleshooting.) The MAC ID LED will be ON steadily when the MAC ID address
rotary switches are above 63 and the current address of the ES-TA-3D1 (as
recognized by the DeviceNet controller) was set with the MAC ID address rotary
switches above 63.
4.4 Selecting Auto or Manual Reset Mode
The ES-TA-3D1 is switchable between Auto and Manual reset (factory setting is
Manual). When Manual reset is selected, the E-stop relay may be reset only by a
manual Reset switch. When Auto reset is selected, the E-stop relay automatically
resets whenever power is applied to the device, or at the moment when all E-stop and
Monitor inputs become closed. (The manual Reset switch is ignored when Auto reset
is selected.) Regardless of which reset method is selected, the E-stop cannot be
started unless all starting prerequisites have been met (power to the system, and all
E-stop and monitor inputs closed).
To select reset mode, open the module cover and remove the green Reset Mode
selector from the black socket. Reinsert the Reset Mode selector so that the mode
you select (either AUTO or MANUAL, one printed on each side of the Reset Mode
selector) is facing up. (See Figure 6.)
In all cases, the user must ensure that closing the Emergency Stop switch (in Auto
reset) or manually resetting the ES-TA-3D1 does not initiate a restart (per NFPA 79
Section 9.6.3).
