Heater break alarm output function
The CT module, combined with the CT sensor or TIO module, can output a heater break alarm. It
addition, it can output the alarm independently for each channel when combined with the DO module.
Either one of the two module types can be selected depending on the heater capacity.
(Specify when ordering. No mixture of these two types is allowed.)
See P. 87.
Up to six CT sensors can be connected to one CT module. The input terminals
of the CT module consist of three blocks with one common terminal and two
CT terminals per block.
In addition, as the CT sensor can capture several CT input points/control
channel, the CT module can make easy the detection of a heater break by
connecting two or more CT sensors even when heaters are delta-connected.
For a heater capacity of 30 A or less, the CT module for 0 to 30 A (CT sensor: CTL-6-P-N
using type) should be used in view of the current detection sensitivity.
A heater break alarm can be output as overall outputs ( OR output) from DOs of PCP module
(A or B type). Use the DO module if this alarm needs to be output independently for each
channel.
For details on the output status, see 3.7 DO Module (P. 46) .
Each input channel can be set by the dedicated operation panel or via communication by the
host computer. For details on the setting, see the
Operation Panel Instruction Manual
