GM550 v1043 FCC-IC.doc Revision 2 25
Lockout Settings
Warning, alarm and lockout control is programmed in this menu. The GS550 can be programmed
to generate alarms and lockout for almost all programmed limits, and two-block. Furthermore,
warnings are generated when approaching programmed load limits and rated capacity (when
applicable).
Warning Level
When gross load (regardless of tare value) approaches the maximum limit for a load sensor
the red overload alarm light will flash. The maximum limit for a load sensor is lower of the
operator set limit (Limit Menu) or the WLL if rated capacity indication is used. The proportion
of a limit that must be reached to trigger the overload warning is the warning level. The
default factory setting for the warning level is 90%.
Step 1. Press Menu → Next → Next → Next → Enter → Next → Next → Next→ Next

Alarm Level
All programmed and rated capacity limits and two-block will generate an audible alarm when
the alarm level is reached. In the event of two-block or overload the appropriate alarm light
will light solid. Other alarms will generate an intermittent alarm message on the LCD. The
proportion of a limit that must be reached to trigger an alarm is the alarm level. The default
factory setting for the alarm level is 100%.

Lockout Level
All programmed and rated capacity limits and two-block can generate a lockout signal when
the lockout level is reached. By default the lockout wires carry crane power supply voltage as
long as the display is in safe condition (to inverse lockout polarity see menu page 4G8).
When a lockout level is reached voltage is be cut on all lockout wires linked to the lockout
condition (see menu pages 4G4 through 4G7). The proportion of a limit that must be reached
to trigger lockout is the lockout level. The default factory setting for the lockout level is 105%.
