SM6000 DELTA ELEKTRONIKA BV
July 2003, rev. March 2012 OPERATING MAINTENANCE TROUBLE SHOOTING CALIBRATING Page 4 - 4
Af ter turn ing the units on again, the slaves will be in Re mote CV
mode and the Key lock (see pre vi ous paragraph 2) is ac ti vated.
This is be cause the unit au to mat i cally de tects the pres ence of the
RJ45 con nec tor in CON C (if this ca ble is con nected to an other
unit).
If the RJ45 con nec tor is re moved from CON C when the unit is
turned on, the out put will shutdown to avoid ac ci den tal dam age.
If the ca ble is in serted when the unit is turned on, the out put shuts
down, the unit changes to Re mote CV / CC, the Key lock will be
ac ti vated and the out put will turn back on.
If DIP switch 4 of SW1 is op er ated when the unit is turned on, the
out put will shut down to avoid ac ci den tal dam age.
The max. num ber of slaves is only lim ited by the max i mum to tal
volt age of 600 V (or 1200V for SM300-30 / SM600-10).
13) MASTER / SLAVE PAR AL LEL OP ER A TION
Note: Mas ter / Slave par al lel is not rec om mended for more
than 3 units, con sult fac tory for us ing more than 3 power
sup plies in par al lel.
First con nect out put ter mi nals and test sys tem in
nor mal par al lel op er a tion. En sure that all power
con nec tions are re li able.
Sec ond, switch off all units. To con nect the slaves with the mas ter
via CON B and CON C, use stan dard RJ45 con nec tors ac cord ing
to fig. 4 - 11.
On all units put DIP switch 4 of SW1 in po si tion UP to set the units
in M/S par al lel mode. In this mode the DCF LED, DCF re lay and
DCF sta tus on the slaves are
dis abled be cause the slaves are al ways in CC mode.
Af ter turn ing the units on again, the slaves will be in
Re mote CC mode and the Key lock (see pre vi ous para graph 2) is
ac ti vated. This is be cause the unit au to mat i cally de tects the pres -
ence of the RJ45 con nec tor in CON C (if this ca ble is con nected to
an other unit).
If the RJ45 con nec tor is re moved from CON C when the unit is
turned on, the out put will shut down to avoid ac ci den tal dam age.
If the ca ble is in serted when the unit is turned on, the out put shuts
down, the unit changes to Re mote CV / CC, the Key lock will be
ac ti vated and the out put will turn back on.
If DIP switch 4 of SW1 is op er ated when the unit is turned on, the
out put will shut down to avoid ac ci den tal dam age.
Stack the units to cre ate a min i mum dis tance be tween the units.
Keep the load close to the mas ter.
Use cop per strips (pre ferred) or short thick ca bles to con nect the
units. Make sure the strips are mounted with a min i mum length to
keep the volt age drop be tween a unit and the bus bar be low 10
mV. Also keep the strips close to each other to have a low in duc -
tance.
Not fol low ing these in struc tions can cause in sta bil ity.
The S- and S+ could be con nected to the load if
de sired, but this is not rec om mended be cause of the com plex ity
and pos si ble instability.
14) PAR AL LEL OP ER A TION OF FAST
PRO GRAMMING VER SIONS:
Mas ter / Slave op er a tion is not rec om mended.
Nor mal par al lel op er a tion can give prob lems, each com bi na tion
has to be tested first in com bi na tion with the load.
15) MASTER / SLAVE MIXED SERIES /
PAR AL LEL OP ER A TION
For com plex com bi na tions as mixed se ries - par al lel, al ways use
a MAS TER / SLAVE SE RIES ADAPTER.
See fig. 4 - 12 for an ex am ple of how to con nect 2 units in se ries in
par al lel with 2 units in se ries, con trolled by 1 mas ter.
Set the pro gram ming mode with the knob Re mote / Lo cal on the
front panel. The se rial slaves must be in Re mote CV- and
CC-mode. The par al lel slave must be in Re mote CC-mode and
the CV-potmeter must be fully opened.
Note: A Mas ter / Slave com bi na tion can al ways be
pro grammed, also with the IEEE488/RS232 con trol ler (PSC-488
/ PSC-232 (both δ-prod ucts)).
