Continuous motor expansion valves with enable relay
Some continuous expansion valves require an enable via an additional signal input. For example, the required
signal
- can be generated via a time relay using the pulsed semiconductor relay EEV1 or EEV2 (holding time t of the
time relay 10 sec. < t < 30 sec.) or
- it can be realised using the
"enable relay"
function;
the parameter "
Freigaberel.
" (menu 6-3) must be
configured to "ON" for this: for details, see chapter
Enable relay for motor expansion valves
.
Exception:
The UA 121 E, UA 131 E, KR 160 E and UK 100 E have one relay output "
Static Cooling
" (terminals 63/64) and
two relay outputs for the UK 100 E/ KR 160 E (terminals 63/64 and 73/74).
The enable signal here does not need to be generated via a time relay or using the
"Enable relay"
function; the
"
static cooling
" output can be used
directly
for the enable. For details, see chapter
ATTENTION
Danger of compressor stoppage!
Systems with single compressors where the suction pressure
cannot be regulated to a setpoint via a pack controller can be operated using the "enable relay"
function (see chapter
Enable relay for motor expansion valves
). The hazard warnings listed in this
chapter must be observed.
