4 420HE Installation Manual
Table 1-1 shows which annunciators are used for all combinations of configured primary and secondary units. For
example:
• If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb LED is lit for primary
units, kg for secondary units.
• If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb LED is lit for primary
units, kg for secondary units. There is not an LED for short tons, so the kg LED is used as the secondary
units annunciator.
• If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary units
(tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs are
used as primary and secondary units annunciators.
See Section 3.2.2 on page 17 for more information about configuring primary and secondary display units.
