Notes:
It is possible to use only circuit 1 from EXD-SH2. In this case, the circuit 2 must be disabled (C2 parameter) and the sensors and the valve for the second circuit are not needed.
ModBus communication is described in a Technical Bulletin and it is not covered by this document.

•Refer to the electrical wiring diagram for electrical connections.
•Note: Keep controller and sensor wiring well separated from supply power cables. Minimum recommended distance 30 mm.
•When connecting the wires of the EXV-M… (electrical plug of valves) consider the color coding as follows:
EXV-M…: WH: White; BK: Black; BN: Brown; BL: Blue
•The digital input DI1 (EXD-SH1/SH2) and DI2 (EXD-SH2) are the interfaces between EXD-SH1/2 and upper level system controller if the Modbus communication has not been used. The external digital inputs must be free of potential (dry contact) and shall be operated in function system’s compressor/demand.

Operating instructions
EXD-SH1/2 Controller with ModBus communication capability for electrical control valves
P r e pa r a t i o n f o r S ta r t - u p :
•Vacuum the entire refrigeration circuit.
•Note: EX/CV valves are delivered partially open position. Do not charge system with refrigerant before closure of valve.
•Apply supply voltage 24V to EXD-SH1/2 while the digital input (DI1/DI2) is open. The valve will be driven to close position.
•After closure of valve, start to charge the system with refrigerant.
S e t u p o f pa r a me t e r s :
(need to be checked/modified before system start-up)
•Make sure that digital input (DI1/DI2) is open. Turn on the 24V power supply to EXD-SH1/2.
•Parameters Password (H5), type of function (1Fct), refrigerant type (1u0/2u0), pressure sensor type (1uP/2uP) and valve scaling (1uF/2uF) need to be set according system requirement and only when digital input DI1/DI2 is open. This feature is for added safety to prevent accidental damage of compressors and other system components.
•Once the main parameters have been selected and saved, the EXD-SH1/2 is ready for startup. All other parameters can be modified at any time during operation or in system standby, if it is necessary.

Note: During manual operation, functional alarms such as low superheat are disabled. It is recommended to monitor the system operation when the controller is operated manually. Manual operation is intended for service or temporary operation of valve at a specific condition. After achieving the required operation, set the parameter 1Ho and 2Ho at 0 so the controller automatically operates the valve(s) according to its setpoint(s).

For serial production of systems/units, upload/download key allows the transmission of configured parameters among range of identical systems.
Uploading procedure (storing configured parameters in key):
•Insert the key while the first (reference) controller is ON and press button; the “uPL” message appears followed by “End” message for 5 seconds.
•Note: If the “Err” message is displayed for failed programming, repeat the
E r r o r / A l a r m h a n d l i ng :
above procedure.
Downloading procedure (configured parameters from key to other controllers):
•Turn off power to new controller.
•Insert a loaded Key (with stored data from reference controller) into new controller and turn on the power supply.
•The stored parameters of the key will be downloaded automatically into the new controller memory; The “doL” message appears followed by a “End” message for 5 seconds.
•The new controller with new loaded parameters setting will start to operate after “End” message disappears.
•Remove the key.
•Note: If the “Err” message is displayed for failed programming, repeat the above procedure.

interrupted, this alarm code will be displayed while the valve is closing. |
ACF1 or ACF2: Alarm code (circuit1/2) for “not permitted configuration/ selection” Alarm will be displayed for the following cases:
•If two circuits of the EXD-SH2 are connected to two different type of pressure transducers i.e. 4-20 mA and 0-5 V. It is mandatory that two circuits always are connected to the same type of pressure transmitter technology.
•Temperature control function is possible only with EX4-8 series valves. If other valves are used, then the ACF alarm will be displayed.
•Ratiometric pressure transmitters cannot be selected in conjunction with R744.
Notes:
S e r v i c e / T r o u bl e s ho o ti n g :
•When several alarms are present, the alarms will be shown one after the other on the lower display.
•Pressure sensor error for third party ratiometric pressure transmitters is based on detection of interruption of two wires (5 V and signal 0.5 - 4.5 V). If only third wire (ground) is open/ interrupted, no error can be detected and controller will receive a false signal between 50% and 100% higher. This false signal leads to improper operation of EXD-SH1/2 controller and can lead to system/compressor damage. EMERSON is not responsible in such cases.

Warnung:
•Für die 24V Stromversorgung sind ausschließlich Transformatoren der Klasse II zu verwenden. Die 24V Leitungen dürfen nicht geerdet werden. Wir empfehlen die Verwendung jeweils separater EMERSON Transformatoren für EXD-SH1/2 Regler und die Regler anderer Hersteller, weil unter Umständen über die Erdleitungen Kurzschlüsse entstehen können.
•Wenn EXD-PM angeschlossen ist, ist es notwendig, dass der EXD-SH-Regler und die EXD-PM-Kondensatoren eigene Transformatoren haben.

EXD-SH1/2 Regler mit ModBus Kommunikation für elektrische Regelventile
V o r b e r e i t u n g e n f ür d i e I nb e t r i e b na h me :
•Gesamten Kältekreislauf evakuieren.
•Hinweis: Die Elektrischen Regelventile EX/CV werden halb geöffnet ausgeliefert. Den Kältekreislauf nur bei geschlossenem Ventil mit Kältemittel füllen.
•Die 24V Versorgungsspannung des EXD-SH1/2 einschalten, während die Digitaleingänge (DI1/DI2) offen sind. Das Ventil wird schließen.
•Bei geschlossenem Ventil System mit Kältemittel füllen.
P a r a me t e r e i n s te l l u n g :
(müssen vor dem Starten geprüft und bei Bedarf angepasst werden)
•Stellen sie sicher, dass die Digitaleingänge (DI1/DI2) offen sind. Schalten sie die 24V Spannungsversorgung des EXD-SH1/2 ein.
•Wenn die Digitaleingänge DI1/DI2 offen sind, müssen die Parameter Passwort (H5), Funktion (1Fct), Kältemittel (1u0/2u0), Drucksensortyp (1uP/2uP) und Regelbereich (1uF/2uF) entsprechend den Systemanforderungen eingestellt werden. Dies ist eine Sicherheitsmaßnahme um zu verhindern, dass versehentlich am Verdichter und an anderen Komponenten Schäden entstehen.
•Sobald die wichtigsten Parameter eingestellt und gespeichert sind, ist der Regler EXD-SH1/2 fertig für die Inbetriebnahme. Alle anderen Parameter könne auch während des Betriebes oder im Stand-By Modus verändert werden.

Der Parametereinstellungsmodus ist durch ein numerisches Passwort geschützt. Die Werkseinstellung ist “12”.
Zum starten des Parametereinstellungsmodus:
•Beide Tasten, und für mehr als 5 Sekunden gedrückt halten.
•Im oberen Anzeigefeld wird eine blinkende “0” und im unteren Anzeigefeld “PAS” angezeigt
• gedrückt halten bis “12” (das Passwort) angezeigt wird.
•Mit das Passwort bestätigen.
•Mit oder können die Parameter der Liste nacheinander angezeigt werden.
•Mit kann der Parameter der eingestellt bzw. verändert werden soll ausgewählt werden.
•Mit oder können die Werte vergrößert oder verkleinert werden.
•Durch drücken von wird der Wert zwischengespeichert. Der Wert blinkt für kurze Zeit dann wechselt die Anzeige zum nächsten Parameter.
•Diese Abfolge kann für alle einzustellenden Parameter wiederholt werden.
Um die neuen Werte dauerhaft zu speichern und den Einstellmodus zu verlassen:
• Taste drücken
Den Einstellmodus verlassen OHNE die neuen Einstellungen dauerhaft zu speichern:
•Beide Tasten und drücken: die vorherigen Änderungen werden gelöscht und der Parametereinstellmodus wird geschlossen.
•Eine andere Möglichkeit zum Beenden ohne Speicherung ist mehr als 120 Sekunden ohne eine Tasteneingabe zu warten (TIME OUT).
•Hinweis: Im Parametereinstellungsmodus wird im unteren Anzeigefeld der Parameter und im oberen Anzeigefeld der Wert angezeigt.
Spezielle Funktionen (Reset, clear) und Handbetrieb
•Beide Tasten und für mehr als 5 Sekunden gedrückt halten.
•Eine blinkende “0” wird angezeigt.

Hinweis: Während des Handbetriebes sind Funktionsalarme, wie “Zu niedrige Überhitzung” unterdrückt. Deshalb muss die Anlage in diesem Falle sorgfältig mit anderen Mitteln überwacht werden. Der Handbetrieb ist nur für Test und Servicezwecke vorgesehen. Danach sind für den Automatik Betrieb die Parameter 1Ho und 2Ho auf “ 0” zu setzen so dass der Regler entsprechend den Sollwerteinstellungen arbeiten kann.
