GSM Commander GC0321 User Manual

8.1.8. IF Analog Input
A statement containing this IF condition, will trigger if the analog voltage measured at the terminals
meets the specified requirements.
The user can choose between the following four options:
• Check if Above Threshold
• Check if Below Threshold
• Check if Inside Window
• Check if Outside Window
Thus, if the user chooses “Check if Above Threshold”, then as soon as the analog voltage measured at the
terminals goes above the specified threshold, the statement will trigger. The same applies to the
remaining options, provided their conditions are met.
The user is also able to specify a “Hold Time” for this statement, which is the time that the trigger
condition must continuously be true before it will be allowed to trigger.
The user is able to specify a “Lockout Time” for this statement, which is the time that, after the
statement has triggered, it will not allowed to trigger again until this time has elapsed.
In other words, if you select a “Lockout Time” of 10 minutes, a “Hold Time” of 5 seconds, and choose
“Check if Above Threshold” of 5V, the statement will trigger as soon as the voltage goes above 5V, and
remains above 5V for 5 seconds. It will then start checking the input again after 10 minutes and trigger
once more if the voltage is above 5V for 5 seconds.
If the user selects a “Lockout Time” of zero, the statement will only trigger once (will trigger again when
the trigger condition has changed and becomes true again).
8.1.9. IF Temperature
A statement containing this IF condition, will trigger if the temperature measured at the probe meets the
specified requirements.
The user can choose between the following four options:
• Check if Above Threshold / Check if Below Threshold
• Check if Inside Window / Check if Outside Window
Thus, if the user chooses “Check if Above Threshold”, then as soon as the temperature measured at the
probe goes above the specified threshold, the statement will trigger. The same applies to the remaining
options, provided their conditions are met.
The user is able to specify a “Lockout Time” for this statement, which is the time that, after the
statement has triggered, it will not allowed to trigger again until this time has elapsed.
The user is also able to specify a “Hold Time” for this statement, which is the time that the trigger
condition must continuously be true before it will be allowed to trigger.
In other words, if you select a “Lockout Time” of 10 minutes, a “Hold Time” of 5 seconds, and choose
“Check if Above Threshold” of 30°C, the statement will trigger as soon as the temperature goes above
30°C, and remains above 30°C for 5 seconds. It will then start checking the temperature again after 10
minutes and trigger once more if the temperature is above 30°C for 5 seconds.
If the user selects a “Lockout Time” of zero, the statement will only trigger once (will trigger again when
the trigger condition has changed and becomes true again).
Please Note: To use this option, you need to have a temperature probe connected to the expansion port
of the GSM Commander via a temperature interface module. Also make sure that the correct type of
probe is selected in the “Temperature Probe Configuration” box under the “Settings” tab in the
software.
