Protection category

19 Series - Override & Status indicating modules

Features

Override module - Auto/Off/Low/High

• Override output module intended to permit the

automatic control of two-speed pumps, blowers

or motor groups. Or, in the case of installation,

maintenance or failure, to permit the load

equipment to be turned “Off“ or to run in “Low

speed“ or “High speed“ under “Hand“ control

• 4 function selector switch:

- Auto: directly controlled by the BMS or PLC

- Off: relays permanently Off

- Hand Low: Low speed relay output

permanently On

- Hand High: High speed relay output

permanently On

• 24V AC/DC supply and module inputs

• 35 mm rail (EN 60715) mounting

Application examples:

• control of two-speed pumps, blowers or motor

groups commonly associated with building

management systems

• Low and High output contacts

• 1 feedback output contact

• 35 mm wide

• LED indicator

Wiring diagram

In position “Low”, “High” or “O” (Off) a Yellow LED will flash and the feedback output

(51-52) will open to indicate that the module is not in the “A” (Automatic) position.

Note: If inputs A3 and A4 are on together, A4 takes precedence, and only High output

(13-24) is closed.

Note 1: the operating delay time from opening of contact13-14 and closing of contact 13-24 is about 80 ms, both in Auto position (when the in-put is switched from

A3 to A4) and when the selector is switched from Low to High position.

Note 2: as a consequence, the maximum switching frequency of the output is 3 Hz.

Note 3: In the case of high inertia loads it may be necessary to add a Timer relay to delay the energisation of the Low speed motor contactor (following High speed

running), to allow the motor time to decelerate.
