Vektek Guardian™ User's guide
Overview
The Guardian™ is a wireless alerting system designed to automate pressure monitoring for
hydraulic workholding. The Guardian™ System consists of two pieces, the MACHINE RECEIVER and
the FIXTURE TRANSMITTER. The MACHINE RECEIVER features an LCD display to communicate
with a human operator as well as a digital interface allowing the device to communicate with an
external machine controller or PLC (Programmable Logic Control). The MACHINE RECEIVER is the
hub of the Guardian System.
The FIXTURE TRANSMITTER is a sealed, compact, low power device utilizing two "AA"
batteries. The FIXTURE TRANSMITTER accepts an input from a non‐powered/dry contact sensing
switch via an M8 connector and continuously reports the status of this switch over a data radio link.
Vektek recommends pressure switch, P/N S7‐0750‐00, for hydraulic pressure monitoring. With
Lithium AA batteries, the FIXTURE TRANSMITTER can operate for up to one year between battery
changes, depending upon the duty cycle of the unit and the number of paired MACHINE RECEIVERS.
Any FIXTURE TRANSMITTER can be used with up to 8 MACHINE RECEIVERS. Each
FIXTURE TRANSMITTER must be "paired" with at least one MACHINE RECEIVER to operate. A
FIXTURE TRANSMITTER can be paired and unpaired repeatedly with various MACHINE
RECEIVERS. In a typical installation, a single MACHINE RECEIVER can be used with as many as 32
FIXTURE TRANSMITTERS.
For applications requiring more than 32 FIXTURE TRANSMITTERS per MACHINE
RECEIVER, please contact Vektek at 1­800­992­0236.
Using the MACHINE RECEIVER
IN CYCLE
The machine tool selects a particular pallet through the digital inputs using a 5‐50 VDC
signal to the MACHINE RECEIVER and asserting the IN‐CYCLE input. Once the MACHINE RECEIVER
has the identification and the IN‐CYCLE input, it checks status of the appropriate FIXTURE
TRANSMITTER and changes the status of the outputs according to the FIXTURE TRANSMITTER
condition.
When "in cycle," the MACHINE RECEIVER display appears as shown above. The MACHINE
RECEIVER shows the name and status of the selected FIXTURE TRANSMITTER switch on the
display. The display will also alert the operator to a fault in the idle pallets but does not contain
specific information about the faulted FIXTURE TRANSMITTER (see below).
