Functions of the Relays and Analogue and Digital Inputs and Outputs
SP25-55_User Manual_B8_EN_2012-11-06 24/32
In the case of a 5-minute clock pulse and e.g. 14 hours of sunshine, approx. 168 entries are generated
every day. After roughly 29 days, the data logger is full and begins overwriting the first data entries
stored: these entries should therefore be read out before they are overwritten.
The inverter's memory for logger data has a storage capacity of 30 Kbytes.
Possible settings:
The 8 parameters available can be used to configure the content of a data logger line as desired. The
minimum parameter number in each case is 0, the maximum number 254. Please refer to the
appendix for the parameter numbers.
Note that the list of parameters from 133 to 140 begins with values that are not zero. The first entry
that is 0 means the end of the logger list. The inverter now creates "files" every day, which the inverter
saves to guard against loss in the event of a power failure.
N.B.:
After you have changed the configuration of the data logger (that is, the content of parameters
133 to 140), you have to delete the entire data logger memory. You do this by setting parameter
66 "Set default values" to the value 70 = Delete data logger.
All changes to the settings of the data logger can be made under password level 1 (Customer).
17 Functions of the Relays and Analogue and Digital Inputs
and Outputs
17.1 Function of relay 1
Parameter 46: Relays 1 function
Menu: Output control
Unit: ---
Resolution: 1
Default setting: 1
Password level: 1
Relay 1 has one N.O. and one N.C. contact. The relay can be used to forward messages to external
units. This relay can also be used to implement alarm (warning) and fault alarm functions. Other
functions will follow in the future and you may send us suggestions or requests for such functions. The
contact rating is 230V AC or 30V DC, max. 5 A.
The connector pin assignments are as follows: (Pin 1 is on the left)
X5, pin 1 Relay 1, two-way contact COM
X5, pin 2 Relay 1, N.O. contact
X5, pin 3 Relay 1, N.C. contact
