M24 – PULSES (PULn, n=1...6)
P24.n.01 Pulse source
P24.n.02 Counting unit
P24.n.03 Pulse duration
Note: This menu is divided into 6 sections, for the generation of energy consumption pulse variables PUL1...PUL6.
P24.n.01 – Defines which energy meter should generate the pulse of the 6 possible meters managed by the DCRG8.
kWh = Active energy; kvarh = Reactive energy; kVAh = Apparent energy.
P24.n.02 – The quantity of energy which must accumulate for pulse emission (for example 10Wh, 100Wh, 1kWh, etc.).
P24.n.03 – Pulse duration.
Application example: For every 0.1 kWh output, a pulse of 500ms has to be generated on output OUT10.
First of all, an internal pulse variable needs to be generated, for instance PUL1. So , section 1 of this menu is programmed as follows:
P24.1.01 = kWh (active energy)
P24.1.02 = 100Wh (corresponding to 0.1 kWh)
P24.1.03 = 0.5
Now, output OUT10 (in menu M04) is set as follows linking it to pulse variable PUL1 above:
P04.10.01 = PULx
P04.10.02 = 1 (PUL1)
P04.10.03 = NOR.
M25 – USER ALARMS (UAn, n=1...8)
P25.n.01 Alarm source
P25.n.02 Channel number source x
P25.n.03 Text
Note: This menu is divided into 8 sections for user alarms UA1...UA8.
P25.n.01 – Defines the digital input or internal variable that generates the user alarm when it is activated.
P25.n.02 – Channel number x relative to the previous parameter.
P25.n.03 – Free text that appears in the alarm window.
Application example: User alarm UA3 must be generated when input INP5 closes and must display the message 'Doors open'.
In this case, set the section of menu 3 (for alarm UA3) as follows:
P25.3.01 = INPx
P25.3.02 = 5
P25.3.03 = Doors open.
M26 – ALARM PROPERTIES (ALAn, n=1...30)
P26.n.01 Alarm enable
P26.n.02 Retentive
P26.n.03 Operating mode
P26.n.04 Global alarm 1
P26.n.05 Global alarm 2
P26.n.06 Global alarm 3
P26.n.07 Step disconnection
P26.n.08 Slave disconnection mode
P26.n.09 Inhibition from input
P26.n.10 Modem call
P26.n.11 Not shown on LCD
P26.n.12 Alarm delay
P26.n.13 Delay UoM
P26.n.01 – Enabled - General enabling of the alarm. If the alarm is not enabled, it is not considered as if it did not exist.
P26.n.02 – Retentive - Remains stored even if the cause of the alarm has been eliminated.
P26.n.03 – Operating mode – Operating mode in which the alarm is generated.
P26.n.04...P26.n.06 – Global alarm 1 -2 -3 – Activates the output assigned to this function.
P26.n.07 – Step disconnection mode – Defines whether and how the capacitor steps must be disconnected when the alarm is present. Choice among:
OFF = no disconnection; SLOW = gradual disconnection; FAST = Immediate disconnection.
P26.n.08 – Slave disconnection mode – For Master-Slave applications, if this alarm arises, it defines whether the disconnection is extended to all the steps of
the system (GENERAL) or only to the output of the involved panel (LOCAL).
P26.n.09 – Inhibition - The alarm can be temporarily disabled by activating an input that can be programmed with the inhibit alarm function.
P26.n.10 – Modem call - A modem is connected as configured in setup.
P26.n.11 – No LCD - The alarm is normally managed, but not viewed on the display.
P26.n.12 – P26.n.13 – Delay time - Time delay in minutes or seconds before the alarm is generated.
