USB-Serial Conversion Cable

Note: A driver must be installed in the personal computer. Refer to

installation information in the operation manual for the

Conversion Cable.

Communications Specifications

* The baud rate, data bit length, stop bit length, and vertical parity can

be individually set using the Communications Setting Level.

Ratings

Heater Burnout Alarms, SSR Failure

Alarms, and Heater Overcurrent Alarms

*1. For heater burnout alarms, the heater current will be measured

when the control output is ON, and the output assigned to the

alarm 1 function will turn ON if the heater current is lower than the

set value (i.e., heater burnout detection current value).

*2. For SSR failure alarms, the heater current will be measured when

the control output is OFF, and the output assigned to the alarm 1

function will turn ON if the heater current is higher than the set

value (i.e., SSR failure detection current value).

*3. For heater overcurrent alarms, the heater current will be

measured when the control output is ON, and the output assigned

to the alarm 1 function will turn ON if the heater current is higher

than the set value (i.e., heater overcurrent detection current

value).
