Interconnection
Upper and Lower Threshold, (menus 13 and 14) and the accompanied delays (menus 15
and 16).
Initially the solid-state output is disabled for both signal output and fault/failure output
(menu 17). When the solid-state switch is to be operated as fault/failure output (for
example, for a separate shutdown system), we recommend disabling the operation for
signal output (select Disabled Mode in menu 17 on page 70). There is no delay in the
operation for fault/failure output.
Switch Protection (Diode)
Factory Settings
The SITRANS LC 500 has a number of default factory settings. If the required settings for
the application are known, the settings can be modified during final testing.
Settings:
Notes:
• The solid-state output should only be used in circuits where the current is limited
by a proper load.
• Due to the limited switching capabilities of the solid-state switch component, an
auxiliary relay must be applied when switching high-current/high-voltage
apparatus.
WARNING: When the solid-state switch is activating an external
relay, protection diodes must be connected in the correct polarity
across the relay coil to prevent possible switch/relay damage
resulting from inductive spikes generated by the relay coil.
Note: To restore factory settings, use menu item 12 (see Factory Settings on page 72
for details).
