EXAMPLE 2 – FARM GATE -or- COOL-ROOM DOOR WARNING
The gate occasionally gets left open or unlatched, leading to loss of stock, intruders, or the cool
room running overtime to maintain the temperature.
1. Connect a reliable sensor or switch to detect the latch action.
Ideally it should be an N/C switch
– so that you’ll be notified if the wiring is broken accidentally.
2. Choose a spare input. Let’s use input # 2
Set it for N/C operation
SET INC 2
3. Give the input some helpful identification.
INON 2 The gate is open
INOFF 2 The gate is closed
4. As a door, it sometimes takes a minute or two to carry things through, so sending a notification
as soon as it is opened would be a waste of time. The farm gate could be ‘closed’, but rattling
against the latch in the wind. Let’s add some hysteresis delays
SET ONDEL 2 2mins
SET OFFDEL 2 30secs
5. I want John (CLI #4) to be notified when the gate is changes state.
SET INSMS 4 2 This means only input #2 changes will contact user #4.
If John wants to receive other input messages we would combine the input numbers – like:
SET INSMS 4 023 - for notifications from inputs 0, 2 & 3
That’s all.
Hang on… let’s add a warning light to indicate the door has been left open.
6. Connect the light circuit to a spare relay output – let’s use output #3
and give it some information…
SET OUTON 3 Warning Light ON
SET OUTOFF 3 Warning Light OFF
7. Associate the gate input #2 events with the warning light output #3
SET ONCMD 2 out 4 on
SET OFFCMD 2 out 4 off
8. We don’t need SMS messages if the light relay changes state, but in a pinch we could ask to see
if it’s on or off with:
SHO OUT 4 to return the current output states.
EXAMPLE 3 – START & STOP AN ENGINE
We’ll stick with ’user John Smith’ for this example.
This example can happily co-exist with the farm gate on the same ControlMate.
1. The generator set requires a 5-second pulse on output #0 to initiate the start sequence, and a
20 second pulse on output #1 to stop & spin-down the engine.
SET PUL 0 5 secs
SET PUL 1 20 secs
