Note: If “ CC/CV Controlled ” displays on this menu’s screen, you will not be able to adjust the
settings as “ CC/CV ” has been selected as the battery type from the 07A Battery Type menu.
Info: The METER: 05A BMK SOC menu’s meter must have a valid SOC number for the
Bulk Start – SOC feature to determine when to start the Bulk charge cycle based on
the battery SOC. Under the METER: 05A BMK SOC menu, Think’n, No Comm, or any
BMK fault (i.e., Factory Fault, Power-up Fault, or Unknown Fault ##) are not valid SOC
numbers.
Where should I set Bulk Start – SOC? Most battery manufacturers recommend that a deep-
cycle battery should not be discharged below 50% SOC. Set the Bulk Start – SOC level to 50%,
or if you do not want to discharge the batteries quite as much, set it to 60% SOC.
PT Relay Engage/Disengage: The PT Aux Relay has three contacts, N.O. (Normally Open),
COM (COMmon), and N.C. (Normally Closed). This means this relay has two sides; COM to
N.O. is one side, and COM to N.C. is the other side. Having two sides means either side can
be open or closed at any time, so using the terms “open” or “close” doesn’t appropriately
describe the relay status.
When describing this relay’s contact status or operation, the terms “engage” (or “engaged”)
and “disengage” (or “disengaged”) are used. When the PT controller energizes the relay to
engage, the COM to N.O. contact closes, and the COM to N.C. contact opens. When the PT
Aux Relay is no longer energized, it disengages, the COM to N.O. contact opens, and the COM
to N.C. contact closes.
• 07E PT Relay VDC – The Aux Relay in the PT controller becomes a battery voltage-controlled
relay when VDC is selected from the CTRL: 05B PT Aux Relay menu. It can be programmed to
engage or disengage on DC volts with an adjustable delay using the following settings.
Note: If more than one PT controller is connected in your system, you can view/edit the data for
each individual controller. See Figure 12-8 for instructions on navigating this menu.
◊ Relay Engage VDC – This setting is the battery voltage trip point at which the Relay
Engage Delay time begins. Once the battery voltage has reached this setting continuously for
the duration of the Relay Engage Delay setting, the PT Aux Relay contacts will engage (N.O.
to COM closed, N.C. to COM opened) . This setting can be below or above the Relay Disengage
Volts setting, depending on if you want the PT Aux Relay to work as active low or active high.
Default setting: 10.0 VDC (12V), 20.0 VDC (24V), 40.0 VDC (48V)
Range: 8.0-17.0 (12V), 16.0-34.0 (24V), 32.0-68.0 (48V)
◊ Relay Engage Delay – This setting determines how long the Relay Engage Volts parameter
must be continuously maintained before the PT Aux Relay engages. Use this setting to delay
the time that the relay engages once the battery voltage trip point has been reached—so the
PT Aux Relay does not cycle unnecessarily .
Default setting: 10 Sec
Range: 0-127 Sec, 1-127 Min (1-sec increments up to 127 sec, then 1-min increments)
◊ Relay Disengage VDC – This setting is the battery voltage trip point at which the Relay
Disengage Delay time begins. Once the battery voltage has reached this setting continuously
for the duration of the Relay Disengage Delay setting, the PT Aux Relay contacts disengage
(N.O. to COM opened, N.C. to COM closed). This setting can be below or above the Relay
Engage Volts setting, depending on if you want the PT Aux Relay to work as active low or
active high .
Default setting: 14.0 VDC (12V), 28.0 VDC (24V), 56.0 VDC (48V)
Range: 8.0-17.0 (12V), 16.0-34.0 (24V), 32.0-68.0 (48V)
◊ Relay Disengage Delay – This setting determines how long the Relay Disengage Volts
parameter must be continuously maintained before the PT Aux Relay disengages. Use this
setting to delay the time that the relay disengages once the battery voltage trip point has
been reached—so the PT Aux Relay does not cycle unnecessarily .
Default setting: 10 Sec
Range: 0-127 Sec, 1-127 Min (1-sec increments up to 127 sec, then 1-min increments)
