PL9710 Indicators with PL9774 Limit Setpoint Option
For Model PL9710 Indicators used with a Model PL9774 Limit
Setpoint module, the following instructions apply.
NOTE: For dual limit setpoint applications, Model PL9710 indicators must be
ordered with the dual limit setpoint option software installed. Standard PL9710
indicators will not contain this option software, it must be added by Rice Lake
Weighing Systems.
System Configurations
The PL9774 Limit Setpoint option may be used with single channel
on-board scale system configurations (3, 4, 5 or 6-point load cell
kits) connected to indicator channel one (CH-1). Also tractor/trailer
scale systems using PL9710 indicator set for dual channel operation
(CH-1, CH-2, TOTAL) may also be configured with the PL9774 Limit Setpoint option. However, limits are only
operable in the Total Gross weight mode. Limit Setpoint control for each individual channel of a dual channel
indicator is available by special order only.
Limit Module Connections
Model PL9774 Limit Setpoint Module is typically supplied with an 8 ft (2.43 m) lead for inter connection to the
PL9710 indicator, and a 15 ft (4.57 m) lead for inter connection to lights/alarms and light/alarm power source.
