Note 5. Relay Action (for Multi-Step Mode Only*):
This is the smoke generator output
setting. This parameter determines which steps to initiate on the smoke generator output.
Its configuration range is from 0 to 63, determined by the following formula:
Relay Action = A * 1 + B * 2 + C * 4 + D * 8 + E * 16 + F * 32;
If A = 0, smoke generator output is OFF at Step 1.
If A = 1, smoke generator output is ON at Step 1.
If B = 0, smoke generator output is OFF at Step 2
If B = 1, smoke generator output is ON at Step 2.
If C = 0, smoke generator output is OFF at Step 3.
If C = 1, smoke generator output is ON at Step 3.
If D = 0, smoke generator output is OFF at Step 4.
If D = 1, smoke generator output is ON at Step 4.
If E = 0, smoke generator output is OFF at Step 5.
If E = 1, smoke generator output is ON at Step 5.
If F = 0, smoke generator output is OFF at Step 6.
If F = 1, smoke generator output is ON at Step 6.
Example:
To turn on the smoke generator output on step 2 and step 3 only, this parameter needs to
be set to 6. (0 * 1 + 1 * 2 + 1 * 4 + 0 * 8 + 0 * 16 + 0 * 32 = 6.)
To turn on smoke generator output on step 1 only, set this parameter to 1.
*: This parameter is only available for multi-step mode (Program Mode = ON). For single
step mode (Program Mode = OFF), smoke generator output is disabled.
Relay Action
parameter can still be adjusted but not in use. To use the smoke generator in single step
mode, users need an extra power cord to power and control the smoke generator
separately from this controller.
Note 6. P:
Proportional Constant. The unit is 1 degree. This parameter controls the
output of the controller based on the difference between the measured and set
temperature.
The larger the P value, the weaker the action (lower gain).
If P = 7, the
proportional band is 7 degrees. When the sensor temperature is 7 degrees below the
proportional band (10 degrees below the setting), the controller will have 100% output.
