SM6000 INSTALLATION
rev. June 2018 DELTA ELEKTRONIKA B.V. Page 4 - 2
• By press ing the DIS PLAY CV/CC SETTING but ton the me ters
will show the set ting of the CV and CC po ten ti om e ter.
• By press ing the DIS PLAY LIMITS but ton the volt me ter will show
the set ting of the CV-limit and the CC-limit potentiometer.
• Check that the cool ing of the unit is not ob structed.
5) KEY LOCK
• If the func tion KEYLOCK is ac ti vated, it is no lon ger pos si ble to
op er ate the RE MOTE/LO CAL but ton and the OUT PUT ON/OFF
but ton. This func tion can be use ful to pro tect the out put from ac ci -
den tal shut down. The func tion KEY LOCK does not in flu ence the
operating of the CV, CC, CV-limit and CC-limit po ten ti om eters.
• Units with dig i tal encoders:
For SM300-20 / SM600-10 and units with Op tion P220, also the
dig i tal encoders for CV and CC are dis abled with the Keylock
func tion. This means set tings of the volt age and cur rent do not
change when the encoders are op er ated. It is still pos si ble to op -
er ate the an a log CV-limit and CC-limit po ten ti om eters.
• Ac ti vate Key lock:
Pressing the but tons DIS PLAY SET TINGS and DIS PLAY
LIMITS at the same time for more than 3 sec onds, ac ti vates the
func tion KEY LOCK. The mo ment this func tion is ac ti vated, the
LED’s for RE MOTE CV / CC and for OUT PUT ON will blink a few
times.
• Dis able Key lock:
Pressing the same but tons again for 3 sec onds, dis ables the Key -
lock function. The LED’s for RE MOTE CV / CC and for OUT PUT
ON will blink again to in di cate the new set ting.
6) SE LECT START-UP MODE
The be low is only ap pli ca ble for SM300-20 / SM600-10 and units
with mag netic encoders - op tion P220.
• Set ting switch SW1-5 at the rear panel in po si tion DOWN, the unit
will al ways start at 0V / 0A af ter mains switch on.
• Set ting switch SW1-5 in po si tion UP, the set tings af ter mains
switch on will be the same as be fore switch ing the mains volt age
off.
7) AN A LOG PRO GRAMMING
• Set DIP switch 1 of SW1 in po si tion UP to se lect CON E for pro -
gram ming. For SM300-20 / SM600-10 see para graph ISO-AMP.
• Dis able Key lock.
• Set the unit in RE MOTE CV for volt age pro gram ming and/or in
RE MOTE CC for cur rent pro gram ming.
Use the RE MOTE/LO CAL but ton and push this but ton sev eral
times un til the right set ting is ac ti vated.
Note that pushing the RE MOTE/LO CAL but ton will shut down the
out put to avoid ac ci den tal dam age to the load.
• Con nect the pro gram ming volt age source(s) (0 - 5 V) to the an a -
log pro gram ming con nec tor CON E on the rear panel (see fig.
4 - 2 and fig. 4 - 3). Al ways use a shielded ca ble (max. 30 me ter)
for pro gram ming.
• Turn the out put on again with the OUT PUT ON/OFF but ton.
• If only the volt age is pro grammed, the max i mum cur rent can still
be set with the CC knob on the front panel and vice versa. If this is
not de sir able the unit can be or dered with Op tion P001 or Op tion
P220 in or der to have a fixed set ting for the CV and the CC knob
on the front panel, see also par. 34) in pre vi ous chap ter "Gen -
eral".
• To avoid hum or noise, the pro gram ming ca ble may have to be
twisted in some cases.
• To pro gram the unit by cur rent in stead of volt age, sim ply use a
par al lel re sis tor as a cur rent to volt age con verter.
• Pressing the DIS PLAY SET TINGS but ton will show the pro -
grammed val ues for CV and CC.
• CAU TION: The an a log in puts are not iso lated from the out put.
The Ø of the prog. in put (pin 1) is in ter nally con nected to the S–,
the S– is con nected to the neg a tive out put. To pro tect the in ter nal
wir ing a 650 mA self-resetting fuse is con nected in se ries (F27_1
on P598). To avoid earth loops, use an iso lated pro gram ming
source. If this is not pos si ble, see nest para graph 8) for us ing the
op tional ISO AMP CARD.
