X
s
Desired temperature in °F x 10 R
p
Desired temperature output is °F x 10
Y
i
Reading controller output and actual value, R
t
Self tuning with take over of controller output in °F x 10
actual value in °F x 10
Note: the letter ”l” means the small type of “L”
Additional instruction for the RS485 interface:
Requirements to the master system during half-duplex operation:
1. After an inquiry, the bus should be switched into a transmission time of 3 bits
(some older interfaces are not fast enough for this).
2. The pyrometer's response will follow after 5 ms at the latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be repeated.
After receiving the response, the master has to wait at least 1.5 ms before a new command can be entered.
