When the solid-state switch is to be operated as a fault/failure output (for example, for a
separate shutdown system) we recommend disabling the operation for signal output
(select Free Programming Mode at menu 1E, and Disabled Mode in menu 17 on page 77).
When the solid-state switch control is disabled at menu 17, the threshold delay settings
are unavailable.
See page 96 for details of a typical application using Pointek CLS500 to provide a high
alarm via the current loop, and a high-high alarm using the solid-state switch.

Factory Settings
Pointek CLS500 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
for details).
