ECKELMANN Case Controller UA 4 E Series - Necessary and Optional Sensors

5.5.1 Necessary and optional sensors
Depending on the controller type and the operating mode, there are necessary and optional sensors for the
case controller. A sensor scan is performed automatically during the first start of the controller. The number of
scanned sensors can be checked in the menu (6-1) or with the LDSWin PC software. This allows unconnected
sensorstoberemovedfromthemonitoringforsensorfault.
The following lists show required and optional sensors in the complete design:

ATTENTION
Compressor damage! Danger due to liquid refrigerant on the suction side of the compressor!

failure of the CAN bus transmission. In standalone operation (without local pressure transmitter),
the sensors, R5.1 and R5.2 must be connected; see chapter Standalone operation using
evaporator inlet sensors!
Operatingmodet

local Z1 / Z2 (menu 6-2-6)
In the case of evaporators with high cooling capacity which require high control dynamics, the
superheat control should be realised via a local pressure transmitter (only UA 410 E AC); see
chapters Standalone operation using activated local pressure transmitter and Emergency Op..
Superheat control only via sensors R5.1 and R5.2 is not recommended, as there is a risk of
evaporator flooding due to the slow response behaviour!
