• The simulate switch enables or disables simulated alerts and
simulated AI Block status and values. The default simulate switch
position is enabled.
• The Security switch allows (unlocked symbol) or prevents (locked
symbol) any configuration of the transmitter.
• Default security is off (unlocked symbol).
• The security switch can be enabled or disabled in software.
Use the following procedures to change the switch configuration:
Procedure
1. If the transmitter is installed, secure the loop, and remove
power.
2. Remove the housing cover opposite the field terminal side.
Do not remove the instrument cover in explosive atmospheres
when the circuit is live.
3. Slide the security and simulate switches into the preferred
position.
4. Reattach transmitter housing cover; it is recommended the
cover be tightened until there is no gap between the cover and
housing to comply with explosion proof requirements.
3.3 Setting simulate switch
The simulate switch is located on the electronics. It is used in
conjunction with the transmitter simulate software to simulate
process variables and/or alerts and alarms. To simulate variables
and/or alerts and alarms, the simulate switch must be moved to
the enable position and the software enabled through the host. To
disable simulation, the switch must be in the disable position or the
software simulate parameter must be disabled through the host.
