Room thermostats in the AMDR series operate on the principle of liquid expansion. A tem- perature change in the liquid-filled sensing system, which consists of probe, capillary and diaphragm, produces a volume change. The resulting movement of the diaphragm oper- ates a microswitch through a lever mechanism. AMDR-1 Switching action TR and TW If the temperature at the probe exceeds the set limit, the circuit is opened through a snap- action switch. If the temperature falls below the set limit (by the switching differential), the switch returns to its initial position. Types AMDR-1 temperature controller TR switching point externally adjustable AMDR-2 temperature monitor TW switching point adjustable after removing the blanking plug AMDR-2 Technical data Electrical data Switching element 1-pole microswitch with changeover contact Max. rating terminal 2: 16 (3) A, 230 V AC +10%, p.f. = 1 (0.6) terminal 4: 8 (1.5) A, 230 V AC +10%, p.f. = 1 (0.6) 0.25 A, 230 V DC +10% max. current surge: 16 A, p.f. = 0.6 2 Electrical connection after removing case cover, at screw terminals up to 2.5mm conductor cross-section Operating data Control ranges 0 to +50C or -10 to +40C Switching point accuracy 0.75C at +20C Switching differential 1 2C Permissible ambient temp. in operation: -20 to +60C Permissible storage temp. -50 to +50C Nominal position (NL) to DIN 16 257, NL 0 NL 90 (other NL on request) Case Case plastic case in impact-resistant polycarbonate color: cover gray beige, RAL 1019 base/setpoint knob light brown RAL 8025 Case fixing by 2 screws on the inside of case Cable entry as standard: clamping gland M 20 x 1.5, for 8 10 mm cable diameter Enclosure protection EN 60 529-IP54 Temperature probe coiled probe, tinned copper Weight approx. 0.35 kg 09.02/00085842M.
