The GS820 System
2.1d Lockout Settings
Warning, alarm and lockout control is programmed
in this menu. The GS820 can be programmed to
generate alarms and lockouts 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, an intermittent warning message is
generated on the LCD. The maximum limit for a
load sensor is the lower of; a) the operator set limit
(Limit Menu), and b) the working load limit (WLL) if
rated capacity charts are 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%.

lockout wires carry crane power supply voltage as
long as the display is in safe condition (to inverse
lockout polarity see menu 4G) 8) L
OCKOUT RELAY
INVERTED). When a lockout level is reached voltage
is cut on all lockout wires linked to the lockout
condition (see menu 4G) 4) through 4G) 7)). The
