CHAPTER 3 BASIC OPERATION
E5CK

•
When the output unit is pulse output such as relay output, set the pulse
output cycle (control period). Though a shorter pulse period provides
better control performance, the control period should be set taking the
life expectancy of the output unit into consideration when the output
unit is relay.
•
The control period is set in the “control period (heat)” parameter (level
1 mode). Factory setting is “20:20 seconds.”
In this example, let’s set the parameters as follows:
“control output 1 assignment” = “control output (heat)”
“control output 2 assignment” = “alarm output 1”
“direct/reverse operation”
= “reverse operation”
“control period”
= “20 seconds”
All of the above settings in this example are factory settings. So, in this
example, we are only going to check the parameter settings.
(1) Select the menu display, and select [
] (setup mode) using the
or
keys. For details on selecting the menu display, see page
1-7.
(2) Press the
key to enter the setup mode. The top parameter in the
setup mode [
] “input type” is displayed. In this example, the
parameter setting is “17: 4 to 20 mA.”
(3) Press the
key until [
] (“control output 1 assignment”
parameter) is displayed. The parameter default is [
].
(4) As the setting in this example is to be left as it is, press the
key.
The display changes to [
] (“control output 2 assignment”
parameter). The parameter default is [
].
(5) As the setting in this example is to be left as it is, press the
key
until [
] (“direct/reverse operation” parameter) is displayed.
The parameter default is [
].
(6) As the setting in this example is to be left as it is, press the
or
keys to select [
] (level 1 mode). For details on selecting the menu
display, see page 1-7.
(7) Press the
key to enter the level 1 mode. The top parameter in the
level 1 mode [
] “AT execute/cancel” is displayed.
(8) Press the
key until [
] (“control period” parameter) is dis-
played. The parameter default is “20”. As the setting in this example
is to be left as it is, quit key operation.
