Description

IN8

Input IN8 status: OFF = Inactive, ON = Active,  Flash = Fault

1

K1

Relay K1: ON = Energized

K2

Relay K2: ON = Energized

K3

Relay K3: ON = Energized

K4

Relay K4: ON = Energized

1. If this input is defined, every three seconds the LED is pulsed to its opposite state for 0.1 seconds, otherwise, the LED is off.

2.11 IT security

Ensure that the LP4502 is installed securely. Create user accounts to the web configuration page using 
secure passwords.

Ensure all DIP switches are to be in the 

OFF

 position for the normal operating mode.

The LP4502 is shipped from the factory with a default login account, which is enabled when DIP 1 is moved 
from 

OFF

 to 

ON

 (See 

DIP switches

).  The default login user name (admin) and password (password) will be 

available for five minutes once the DIP switch is toggled.  It is therefore important that at least one user 
account is defined, and the DIP switches are set to 

OFF

 before the LP4502 is commissioned.

Configuring the LP4502 with an IP address that is accessible from the public is 

not

 recommended.

The following options are available for enhanced network security:

 

n

Disable SNMP.

 

n

Zeroconf discovery.

 

n

The web configuration module.

 

n

Enable data encryption over the host communication port.
