OPERATING MANUAL
1) OP ER ATING THE UNIT FOR THE FIRST TIME
• Check there is no con den sa tion on the unit. If there is, al low some
time to dry.
• Check there is a link be tween + and S+ and be tween – and S– on
the SENSE BLOCK (on rear panel).
• Check there is a link be tween the in puts of the In ter lock (CON A,
rear panel).
• Set the CV and CC po ten ti om eters to min i mum (fully anti clock -
wise).
• For rec om mended ca ble di am e ters and torque (see table 4 - 1)
• With high out put cur rent make sure to use low re sis tive con -
nec tions be tween the power sup ply and the load:
- Mount the ca ble lugs di rectly on the tinned out put strips
fol lowed by a washer, a split washer and a nut (see fig. 4 - 1).
Al ways in this or der!
- Never place wash ers be tween the lugs and the strips
be cause this can re sult in ex ces sive heat!
- Only use nuts and wash ers sup plied with the unit.
• Switch on unit.
• Dis able the Key lock func tion, see next para graph 2).
• Check the unit is not in Re mote CV or Re mote CC (LED’s for this
func tion should be off). Press the RE MOTE/LO CAL but ton un til
both LED’s are off.
• Turn on the out put by press ing the OUT PUT ON/OFF but ton.
• Turn both the CV and CC po ten ti om e ter a few turns clock wise.
A volt age should now be pres ent on the out put.
• 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 the cool ing of the unit is not ob structed.
2) KEY LOCK
• If the func tion KEY LOCK 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 potentiometers.
• 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.
3) AN A LOG PRO GRAM MING
• Set dipswitch 1 of SW1 in po si tion ON to se lect CON E for pro -
gram ming.
• 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 po ten ti om e ter and vice versa. If this is not de -
sir able the unit can be or dered with Op tion P001 in or der to have
a fixed set ting for the CV or the CC po ten ti om e ter on the front
panel.
