The GS375 System
The GS375 System
1.1 Overview
1.1 Overview
The anti-two-block indicator kit includes a GS375
display and one or two wireless anti-two-block
switches. The GS375 creates a two-way radio
network with the anti-two-block(s) to monitor status.
When an anti-two-block switch goes from safe to
alarm condition, the GS375 will activate its alarm
and lockout wires within 0.05 seconds. The lockout
wire can be connected to a relay to block crane
functions such as boom out or hoist up.
1.2 Start-Up
1.2 Start-Up
On power up, the display will take between 5 and
10 seconds to communicate with the anti-two-block
switch(es) it controles. After this period, the main
hoist green light should light up steady. If it still
flashes after 30 seconds, it means communication
is not established. See the section on changing
batteries later in this manual, or the section on
changing ID numbers if the switch has been
changed.
The auxiliary hoist green light works the same as
the main hoist green light, but it applies to the
second anti-two-block switch, if present. The
auxiliary hoist green light will stay “off” if the display
is not programmed to communicate with a second
anti-two-block switch.
