The following steps are to program the Br3 to select and configure the desired function.
1. When there is no function set, as is the case on an initial power on, or if you desire to change the function, the user must first press and
hold both push buttons (INCR & PARAM) for three (3) seconds to activate the display. At this point the display will toggle between
FF
and
00
every one (1) second for five (5) seconds after the last button has been pressed.
2. By pressing on the INCR button, the user can toggle through each function to select the function. A display of
10
corresponds to
function MC10,
11
corresponds to function MC11, etc. Once you reach the last function,
75
, the list will rollover to the beginning.
NOTE: Selecting
00
disables the module.
3. After selecting the function, the user can then press the PARAM button to cycle through and set the parameters defined for that particular
function, if applicable. If there are any function parameters, the display will toggle between the parameter and its current value every
one (1) second for five (5) seconds after the last button has been pressed. If there are no parameters,
NP
and
--
will be displayed as a
parameter and its value for five (5) seconds.
NOTE: Once the PARAM button has been pressed as to set the function’s respective parameters and values, the user will not be able to
go back and select a different function until the display goes inactive and the user repeats the above process starting with Step
1. This prevents the user from inadvertently changing functions or selecting variables from different functions.
4. After selecting the function’s parameter to change, the user can press the INCR button to increment the parameter’s value. A single
press of the INCR button will increment the value by one, but holding the increment button will allow for a rapid increment of the value.
5. Once all parameters for the function are set, wait the five (5) seconds for the display to go inactive and the Br3 to save the updated
parameters. The Br3 is now programmed. As long as no relays are active, the display will show the function selected, otherwise it will
show those relays. Once the values are changed, they are only saved after the display goes inactive again (5 seconds).
NOTE: Remember that the INCR push button always increments the value of the parameter that you are looking at, and the PARAM
push button toggles through the available parameters.
NOTE: To change only the value of a parameter under the function, start the process with Step 3.
5 Selecting the Function
PRECAUTIONS TO OBSERVE WHEN USING A ‘WET’ OUTPUT
Never change the switch settings when the module has power connected to it or when a load is applied.
Never allow 2 different voltage sources to be connected to the load (electric strike for example) at the same time. This can result in serious
damage to equipment.
Always move
both
shunts when changing a jumper set.
If an EL device is being powered by a separate power source, DO NOT select the ‘WET’ output option on the Br3. If ‘WET’ is selected, the
next activation of the module will send a voltage to the load and if there is already a voltage being applied from another source, the Br3 and
possibly the load will be permanently damaged.
When using the ‘WET’ output option on the Br3, set all desired switch positions (‘WET’ – ‘DRY’ and AC – DC) before the module is powered
and before any loads are applied.
When DC ‘WET’ output is selected, COM terminal is po) and the ground(-) is switched between NO and NC.
Ensure there is no other voltage connected to the load. Whatever the Input voltage is at the Br3, the output will correspond. The following
can also be observed:
1. If voltage Input at the Br3 is AC, then output selection can be AC or DC.
2. If voltage Input at the Br3 is DC, then output selection can only be DC.
3. The maximum load applied to Relay 1 should never exceed 1A. If more than one device is to be connected, add the consumption values
together for a total value. If current is excessive, damage to equipment can result.
4. On the Br3, the ‘WET’ output is only available at Relay 1.
When supplying Br3 with AC input voltage, and selecting ‘WET’ output on relay
with
DC conversion, you actually get rectified AC voltage,
which is identical to applying a bridge rectifier to any AC voltage.
CAUTION: Relay 1 ‘WET’ OPTION IS ACTIVE FOR ALL FUNCTIONS!
