SAFETY FIRST

2.0 SAFETY ISSUES

Read all instructions, warnings and cautions

carefully. Follow all safety precautions to

avoid personal injury or property damage

during system operation. Enerpac cannot be responsible for

damage or injury resulting from unsafe product use, lack of

maintenance or incorrect product and/or system operation.

Contact Enerpac when in doubt as to the safety precautions and

operations.

A CAUTION is used to indicate correct operating or maintenance

procedures and practices to prevent damage to, or destruction of

equipment or other property.

A WARNING indicates a potential danger that requires correct

procedures or practices to avoid personal injury.

A DANGER is only used when your action or lack of action may

cause serious injury or even death.

Failure to comply with the following hazard alert statements could

cause equipment damage and/or personal injury:

WARNING: Make no modiﬁ cations to any SafeLink

component. Any modiﬁ cations to the product not

expressly approved by Enerpac could void the user’s

authority to operate the product. Contact Enerpac factory for more

information.

WARNING: SafeLink products must only be serviced by a

qualiﬁ ed electronic technician. For factory authorized

repair service, contact the ENERPAC Authorized Service

Center in your area.

WARNING: Never use any component of the SafeLink

system as a sensing device for personal protection. Doing

so could lead to serious injury or death. The SafeLink

system does NOT include the self-checking redundant circuitry

necessary to allow its use in personal safety applications. A sensor

failure or malfunction can cause either an energized or de-

energized sensor output condition.

WARNING: Some SafeLink components are powered by

a 3.6 volt lithium battery. As with all batteries, there is a

ﬁ re, explosion, and severe burn hazard risk. Do not burn

or expose the battery to high temperatures. Do not recharge,

crush, disassemble, or expose the contents to water.

WARNING: All live supply circuits must be disconnected

before wiring the machine control.

WARNING: To avoid personal injury, keep hands and feet

away from ﬁ xture cylinder(s) and workpiece during

operation.

Note: All speciﬁ cations published in this document are subject to

change. Enerpac reserves the right to modify the speciﬁ cations of

products without notice. Enerpac reserves the right to update or

change documentation at any time.

6.0 INSTALLATION 6.3 Installing the SLS-1 Send Unit on a Fixture 6.1 Overview The SLS-1 send unit must be mounted externally on the ﬁxture in a location that does not expose the unit to excessive coolant ﬂow or ﬂying chips. The SafeLink wireless pressure monitoring system continuously monitors the clamping pressure in a ﬁxture during the machining process. It is designed to be interfaced to the machine control so the machine can be stopped immediately if clamping pressure is lost.

Note: The rotary switches on the SLR receive unit are used only to select the desired SLS send unit to be viewed on the receive unit LCD display. They DO NOT determine the send unit ID. Refer to Section 8.4 for additional information. After binding occurs, the SLS send unit will ﬂash BOUND several times and will then begin scrolling. However, it will remain in a standby mode until the SLR receive unit is returned to the RUN mode. 8.

Press Button #1 on RECEIVE UNIT to scroll to site. Display will begin scrolling when RECEIVE UNIT is placed in RUN mode. Press button #2 to begin viewing the selected SEND UNIT. LED #1 will turn GREEN when SEND UNIT begins communicating with RECEIVE UNIT. Press button #2 again to start the survey of the signal strength.

.6 Removing an SLS Send Unit from the Network 9.0 SETTING UP EXPANDED SYSTEMS Before taking a fixture out of service or moving it to another system, the fixture’s SLS send unit must be removed from the network. Refer to Table 6 for an overview of SafeLink expansion possibilities. If only one or two additional SLS send units are required, the SLEM-1 Expansion Unit can be used.

.5 Setting up Ethernet IP Communication Modbus RTU is the native protocol for the SafeLink system. All wireless devices are organized with a two-byte register for each I/O point. Sixteen registers are allocated for each device, typically eight registers for inputs and eight registers for outputs. For Modbus, these registers are addressed consecutively beginning with the Receive (SLR-1 or SLR-2) then Send 1 (SLS-1, SLS-2 or SLS-3) through Send (N) (SLS-1, SLS-2 or SLS-3).
