Usage
Switches:
There are five switches on a GERC_RLY. The first four are used to enable or disable the X, Y,
Z, A axes. They must be up (pointing to the LEDs) to enable an axis.
The rightmost switch is the AllStop/Reset switch. It must be up as well for things to operate.
Down is All Stop (no matter what the state of the other four switches)
Down, then up again, is Reset.
Normal condition, then, is all switches UP.
LEDs:
There are four LED conditions.
Enabled axis
When an axis is ENABLED, the LED for that axis is ON steady.
With all axes enabled, all LEDs are on steady.
With all axes disabled, no LEDs are on.
Normal operation, then, is all LEDs on.
Reset
Any time the unit is reset, the LED for an
enabled
axis will blink slowly for 5 seconds or so. If
all axes are enabled, all the LEDs will blink (in unison). During this time, the Geckos are being
reset, and the fault LEDs on the Geckos (hidden away inside your chassis where you can’t see
them) should go out.
Two things cause a reset.
1. Power turned on.
2. Toggling the AllStop/Reset switch.
Axis fault
Should a Gecko detect a fault condition on an axis during normal operation (things working
fine), the LED for that axis will blink quickly.
A single blinking LED indicates a faulted axis
